--- title: 7 Lost Cities That Were Never Lost description: "Few archaeological discoveries are as revealing, informative, or downright exhilarating as the unearthing of a lost city. After all, these are entire settlements that offer a tangible connection to civilizations and peoples who vanished long ago, forgotten by much of the world. Yet, while many of these sites, like Petra, Machu Picchu, and others, were lost to the outside world, they were never forgotten by the local communities who once called them home. In many cases, people continued living near these ancient cities, preserving a cultural memory of their significance long before outsiders arrived to \"discover\" them. So, today, we'll explore seven of these remarkable cities that never truly needed to be discovered.\n\n## Great Zimbabwe, Zimbabwe\n\nIn the early 16th century, Portuguese explorers in Africa began hearing legends about a mysterious stone castle in what is now Zimbabwe. Locals referred to it as \"Symbaoe\" and said it was a massive stone fortress that rose higher than the surrounding trees. Though they didn't know who had built it, they spoke of it not as myth, but as fact. When word of the fortress reached Europe, however, most Europeans dismissed it as little more than a tall tale. At the time, many couldn't fathom the idea that sub-Saharan Africans were capable of constructing castles akin to those found in Europe. Even when the site was physically rediscovered in the 19th century, many still clung to disbelief and alternative theories emerged, including the claim that it was a long-lost Phoenician or biblical settlement. But as archaeologists began to excavate the site, they quickly realized how little they actually knew about sub-Saharan African history.\n\nIn truth, the ruins belonged to the lost capital of a Bantu-speaking people known as the Shona, who founded an empire now referred to as the Kingdom of Zimbabwe that flourished between the 13th and 15th centuries. \"Zimbabwe,\" meaning \"stone houses\" or \"stone buildings\" in the Shona language. What the explorers had heard about was not just a castle, but instead a vast, sophisticated city, today divided into three major sections.\n\nThe first, known as the Hill Complex, sits atop an acropolis and likely served as the city's religious center, where spiritual rituals were conducted. Some scholars also suggest it may have doubled as a royal residence at times. This is the oldest part of the site, with evidence of construction dating back to around 900 AD.\n\nThe second, and most famous, section is the Great Enclosure, the structure that initially captured European attention. Located below the Hill Complex, this circular walled compound once functioned as the city's central fortress. Its walls soar up to 10 meters (32 feet) high and span a circumference of 250 meters (820 feet). Remarkably, the entire structure was built without mortar; instead, precisely cut stones were carefully stacked to interlock perfectly. This section was constructed in the 14th century, making it the newest part of the city, and only around 200 years old when Portuguese explorers first heard tales of it.\n\nThe third area, the Valley Ruins, is less striking architecturally, consisting mostly of mud-brick houses. However, the sheer number of these dwellings reveals the scale of the settlement. Scholars estimate that Great Zimbabwe may have housed between 10,000 and 20,000 people and was part of a vast trade network. Artifacts found at the site include Chinese and Persian porcelain, glass beads, and Arab coins and gold, all indicative of an empire with extensive international connections.\n\n## Machu Picchu, Peru\n\nHigh in the Peruvian Andes, tucked away in a location unimaginable to most, lies Machu Picchu, the most famous archaeological site in the Americas. In 1911, while searching for Vilcabamba, the last Incan capital, American professor and explorer Hiram Bingham was led to the site by local indigenous farmers who had long known of its existence. Upon arrival, Bingham was stunned to discover a hidden village of Incan homes and temples, many overgrown with moss and encroaching vegetation. Perched 2,400 meters (7,900 feet) above sea level on a steep ridge, the site was crisscrossed by intricate stone terraces. Eager to share his findings, Bingham returned to the United States to publish his discovery, bringing global attention to Machu Picchu and organizing a formal excavation team.\n\nToday, the site has been extensively excavated and studied, and it ranks among the most visited archaeological destinations in the world. Experts believe Machu Picchu was built in the 15th century as a kind of summer retreat for the Incan elite. The site includes over 200 structures including homes, baths, and temples, divided into two main sections: the upper portion, primarily residential, and the lower, largely agricultural. These areas were separated by a large central square but connected by roughly 3,000 stone steps that allowed movement throughout the multi-tiered complex.\n\nThough likely a retreat for the elite, Machu Picchu is thought to have supported about 750 year-round residents, mainly composed of support staff and farmers. Despite its grandeur, the site remained unknown to the outside world for centuries. It is widely believed that the Spanish never discovered Machu Picchu, and it was largely forgotten after the collapse of the Inca Empire in the 16th century. However, this narrative overlooks the local indigenous communities, many likely descended from the Incas who dwelt at Machu Picchu, who continued to live nearby. In fact, Bingham himself was even surprised to encounter a family living close to the site during his ascent.\n\n## Petra, Jordan\n\nIn *Indiana Jones and the Last Crusade*, many viewers were introduced to their first glimpse of Petra, a real-life ancient city nestled in the desert of southern Jordan. Once the capital of the Nabataean Kingdom, Petra was intricately carved from the reddish sandstone cliffs of its surroundings in the 4th century BC, giving the city its iconic pink hue and the nickname \"The Rose City.\" While the Treasury is undoubtedly the most recognizable structure, and often mistaken as the city's main entrance, Petra spans over 264 square kilometers (about 100 square miles), encompassing far more than just this famous façade.\n\nPetra was rich in temples, theaters, and other public buildings, many of which exhibit a striking blend of Hellenistic and Eastern architectural influences. Its location, strategically positioned between the Dead Sea and the Red Sea, allowed the Nabataeans to control a crucial trade route connecting Arabia, Syria, and Egypt. This access helped Petra flourish as a cultural and economic hub for centuries. Beyond trade, archaeological evidence suggests the Nabataeans also mined copper in the surrounding areas, further boosting the city's prosperity. At its peak in the 1st century AD, Petra is believed to have housed around 20,000 residents, as evidenced by the numerous rock-cut tombs and dwellings still visible today. One of Petra's most impressive features was its advanced water management system. Ingeniously engineered to support life in an arid desert climate, the system included tunnels, diversion dams, cisterns, and reservoirs that worked together to supply a stable water source for thousands of inhabitants.\n\nIn the 2nd century AD, the Romans annexed Petra and redirected key trade routes, diminishing the city's economic importance. Despite this, Petra remained occupied, with the Romans, and later the Byzantines, adding their own structures, including several Christian churches. The city is thought to have been gradually abandoned by the 7th or 8th century AD.\n\nThough Petra faded from the world's attention, it was never entirely \"lost.\" Bedul Bedouin communities continued to live near and within the ruins for centuries, often serving as the site's unofficial guardians. In 1812, Swiss explorer Johann Ludwig Burckhardt rediscovered Petra for the Western world. According to accounts, he gained access by disguising himself as a pilgrim and convinced the Bedouins to lead him to the site. When Petra was designated a UNESCO World Heritage Site in 1985, several Bedul families were still living within the ancient city, using its structures as homes and stables. As part of preservation efforts, the Jordanian government relocated these families to a nearby village, yet their legacy as caretakers of Petra remains deeply woven into the site's modern story.\n\n## Sigiriya, Sri Lanka\n\nIn the 5th century AD, Sri Lanka's Moriya dynasty found itself in a period of turmoil. After overthrowing his father and seizing the throne, King Kashyapa was locked in a civil war with his brother Mogallana, the rightful heir. To secure his position and prepare for war, Kashyapa decided to build a nearly impregnable fortress atop a 180-meter (600-foot) granite column, from which he could safely launch his military campaign. According to Buddhist texts, the site was already believed to have been used as a monastery, which Kashyapa believed helped frame his rule as righteous and divinely sanctioned.\n\nAt the base of this towering rock, Kashyapa constructed a grand staircase with a mid-way landing guarded by a colossal brick-and-plaster lion. To continue climbing to the summit, visitors had to pass through the lion's mouth. Today, only the lion's massive paws remain, flanking the stairway, but they're enough to confirm the legendary structure was real. Climbing the 1,200 steps to the top, which are lined with galleries and terraces, visitors would arrive at a breathtaking sight.\n\nSigiriya, as it came to be known, served as Kashyapa's capital and was transformed into a sophisticated citadel. The summit held the main palace complex, surrounded by smaller palaces, homes, terraced gardens, fountains, and even a moat. Inside the king's palace was a \"mirror wall,\" which was polished so finely that Kashyapa could admire his reflection as he walked by. Nearby, a 140-meter (460-foot) long and 40-meter (131-foot) high wall once displayed vibrant frescoes of beautiful women, evidence of which survives through ancient graffiti left behind by early admirers. Sigiriya also featured an advanced hydraulic system, incorporating canals, dams, bridges, and underground pumps that distributed water throughout the gardens and fountains. Remarkably, this system was engineered so precisely that some fountains still operate during heavy rains, delighting modern visitors with the ingenuity of ancient Sri Lankan engineering.\n\nHowever, not long after Sigiriya's completion, Mogallana launched an attack. Kashyapa's army quickly abandoned him, and his wives leapt to their deaths from the rock's edge, rather than be taken alive. The fortress fell swiftly, and the king's mountaintop paradise was left behind. In the years that followed, Sigiriya became a Buddhist monastery, remaining active until the 14th century, and later served as a military outpost for the Kingdom of Kandy in the 16th and 17th centuries. So, when British Army Major Jonathan Forbes \"discovered\" the site in 1831 while horseback riding, and brought it to the wider world's attention, he was merely reintroducing a place that had never been truly forgotten, one remembered by locals and preserved in Buddhist texts for centuries.\n\n## Mesa Verde, US\n\nWhile the United States is often overlooked in the search for lost cities, that doesn't mean it lacks any. Quite the opposite, in fact. Before the arrival of Europeans, millions of Native Americans were already living on the land. The U.S. government officially recognizes 574 different tribes today, though the true number was likely much higher. Many of these peoples built towns and cities, one of the most famous being Mesa Verde in southwestern Colorado.\n\nAt Mesa Verde, more than 600 dwellings were discovered, built from sandstone and mud mortar, carved directly into the cliffs and alcoves of the surrounding canyon walls. This was home to the Ancestral Puebloan people for about 700 years, from around 550 AD to 1300 AD. Though the cliff dwellings are the most iconic feature of Mesa Verde, they represent only a small portion of the site's 4,700 archaeological features and were likely only constructed during the last 75 to 100 years of occupation. Structures across the site vary widely in size, from small storage rooms to large villas capable of housing between 50 to 200 people, some with as many as 150 individual rooms. Among the most famous buildings are the multi-story Cliff Palace, the Balcony House, and Tower Square. However, the site also contains countless pit houses, masonry towers, farming terraces, and field houses. Mesa Verde featured a sophisticated water management system, including check dams, ditches, and reservoirs, as well as numerous shrines and rock art, testament to a highly developed, domesticated culture, whose descendants, the modern Pueblo peoples, maintain many of these traditions today.\n\nAt its peak, Mesa Verde likely supported thousands of residents, though exact numbers remain uncertain. In the late 13th century, the Ancestral Puebloans began migrating, primarily to nearby regions like modern-day New Mexico and Arizona, leaving the site uninhabited. It remained that way until 1888, when two cowboy brothers \"rediscovered\" the ancient city. Yet it was never truly forgotten. Local Indigenous groups, including the Pueblo, Navajo, and Ute peoples, preserved knowledge of Mesa Verde through oral traditions, passing down stories and legends that kept its memory alive. It's even likely that the site continued to be used intermittently over the following centuries, offering temporary refuge from the elements to those who remembered it.\n\n## Angkor, Cambodia\n\nFrom the 9th to the 15th centuries, the Khmer people of Southeast Asia ruled a vast empire that encompassed much of present-day southern Vietnam, Laos, Thailand, and Cambodia. Cambodia served as the empire's heartland, with its now-famous capital, Angkor, located in the northern province of Siem Reap. While Angkor's fame is due in no small part to the stunning temple of Angkor Wat, the city itself offers an extraordinary glimpse into the grandeur and sophistication of the Khmer Empire.\n\nIn addition to Angkor Wat, widely regarded as the largest religious site in the world, the city is home to numerous other temples, including Ta Prohm and Bayon. Many of these were originally dedicated to Hindu deities. However, as the empire gradually transitioned to Buddhism, Buddhist iconography became intertwined with Hindu symbolism, transforming the temples and the city into a unique and beautiful fusion of the two religions. Although the temples are what Angkor is best known for today, the ancient city was once a thriving metropolis. Archaeological evidence suggests that the population may have reached between 600,000 and 750,000 people, with remnants of residential areas still visible across the region.\n\nTo sustain such a large population, the Khmer developed an extensive and sophisticated water-management system that included dykes, massive reservoirs, canals, basins, and an underground drainage network. To connect Angkor with the wider empire, they also built an impressive network of roads, complete with rest houses and stone bridges, much like the Roman infrastructure, linking the provinces back to the capital.\n\nOver time, the Khmer Empire shifted its capital, and years of warfare and gradual decline led to Angkor's eventual abandonment. In the 1860s, French explorer Henri Mouhot famously \"rediscovered\" the ruins. However, this narrative oversimplifies the reality. Angkor and its temples remained important pilgrimage sites for Khmer people, Buddhists, and Hindus alike. While parts of the city were indeed overtaken by jungle, Angkor was never truly lost. In fact, the area is still inhabited today, with nearby villages home to descendants of Angkor's original citizens who never left the region.\n\n## Babylon, Iraq\n\nAbout 94 km (59 miles) southwest of Baghdad, Iraq, lies one of the most important, beloved, and frequently visited cities of the ancient world: Babylon. By the time of the Roman Empire, Babylon's architecture and cultural legacy were already so renowned that the city appeared in biblical texts, most famously in the story of the Tower of Babel, and its legendary Hanging Gardens were counted among the Seven Wonders of the Ancient World. Yet Babylon's history predates the Romans, the Bible, and many of the sources that shaped our modern understanding of it. Located along the lower Euphrates River in southern Mesopotamia, the city is believed to have existed before the reign of Sargon of Akkad (c. 2334–2279 BC), as references to Babylon appear in records from that time, though it likely began as a relatively minor port settlement.\n\nIt wasn't until the reign of Hammurabi (c. 1792–1750 BC) that Babylon rose to prominence. Hammurabi established the city as the capital of his expanding Babylonian Empire, strengthening its defensive walls and initiating major public works, including temples and canals. Under his rule, Babylon grew rapidly, with its population estimated to have surpassed 100,000. After Hammurabi's death, the city fell to the Hittites, then to the Assyrians, and eventually to the Chaldeans, who would form the Neo-Babylonian Empire. During this era, especially under Nebuchadnezzar II, Babylon reached the height of its power and splendor. Some of its most iconic architectural achievements, such as the Ishtar Gate and the fabled Hanging Gardens, are attributed to this period. The population may have exceeded 200,000, marking the city's peak in both size and cultural influence.\n\nEventually, however, the Neo-Babylonian Empire would also fall. In 539 BC, Babylon was conquered by Cyrus the Great who made it the seat of the Persian Achaemenid Empire. Later, in 331 BC, it was captured by Alexander the Great. As centuries passed and empires rose and fell, Babylon endured, until its eventual decline and abandonment, likely by the 7th century AD. Over time, it faded into ruin, buried by sand and time.\n\nIn 1899, German archaeologist Robert Koldewey began formal excavations of the \"lost\" city, though European travelers had encountered the ruins for centuries prior, even if they didn't fully grasp their significance. Yet to locals, Babylon had never been lost. The nearby city of Hillah, located just 5 km (3.1 miles) to the south, has long stood in the shadow of its ancient predecessor. For countless generations, residents grew up with the ruins in plain sight. So, when the wider world began speaking of Babylon's \"rediscovery,\" many locals were left puzzled because, for them, it had never truly been forgotten.\n\n## Key Takeaways\n\n- Local communities preserved cultural memory of ancient cities like Petra and Machu Picchu.\n- Great Zimbabwe was a sophisticated city with extensive trade networks, contrary to European beliefs.\n- Machu Picchu was known to local indigenous communities long before Hiram Bingham's 'discovery'.\n- Petra's advanced water management system supported a large population in an arid desert climate.\n- Sigiriya's hydraulic system, engineered by King Kashyapa, still functions during heavy rains today.\n\n## Frequently Asked Questions\n\n### What is the significance of Great Zimbabwe?\n\nGreat Zimbabwe was the capital of the Shona people's Kingdom of Zimbabwe, which flourished between the 13th and 15th centuries.

After all, these are entire settlements that offer a tangible connection to civilizations and peoples who vanished long ago, forgotten by much of the world. Yet, while many of these sites, like Petra, Machu Picchu, and others, were lost to the outside world, they were never forgotten by the local communities who once called them home. In many cases, people continued living near these ancient cities, preserving a cultural memory of their significance long before outsiders arrived to "discover" them. So, today, we'll explore seven of these remarkable cities that never truly needed to be discovered. ## Great Zimbabwe, Zimbabwe In the early 16th century, Portuguese explorers in Africa began hearing legends about a mysterious stone castle in what is now Zimbabwe. Locals referred to it as "Symbaoe" and said it was a massive stone fortress that rose higher than the surrounding trees. Though they didn't know who had built it, they spoke of it not as myth, but as fact. When word of the fortress reached Europe, however, most Europeans dismissed it as little more than a tall tale. At the time, many couldn't fathom the idea that sub-Saharan Africans were capable of constructing castles akin to those found in Europe. Even when the site was physically rediscovered in the 19th century, many still clung to disbelief and alternative theories emerged, including the claim that it was a long-lost Phoenician or biblical settlement. But as archaeologists began to excavate the site, they quickly realized how little they actually knew about sub-Saharan African history. In truth, the ruins belonged to the lost capital of a Bantu-speaking people known as the Shona, who founded an empire now referred to as the Kingdom of Zimbabwe that flourished between the 13th and 15th centuries. "Zimbabwe," meaning "stone houses" or "stone buildings" in the Shona language. What the explorers had heard about was not just a castle, but instead a vast, sophisticated city, today divided into three major sections. The first, known as the Hill Complex, sits atop an acropolis and likely served as the city's religious center, where spiritual rituals were conducted. Some scholars also suggest it may have doubled as a royal residence at times. This is the oldest part of the site, with evidence of construction dating back to around 900 AD. The second, and most famous, section is the Great Enclosure, the structure that initially captured European attention. Located below the Hill Complex, this circular walled compound once functioned as the city's central fortress. Its walls soar up to 10 meters (32 feet) high and span a circumference of 250 meters (820 feet). Remarkably, the entire structure was built without mortar; instead, precisely cut stones were carefully stacked to interlock perfectly. This section was constructed in the 14th century, making it the newest part of the city, and only around 200 years old when Portuguese explorers first heard tales of it. The third area, the Valley Ruins, is less striking architecturally, consisting mostly of mud-brick houses. However, the sheer number of these dwellings reveals the scale of the settlement. Scholars estimate that Great Zimbabwe may have housed between 10,000 and 20,000 people and was part of a vast trade network. Artifacts found at the site include Chinese and Persian porcelain, glass beads, and Arab coins and gold, all indicative of an empire with extensive international connections. ## Machu Picchu, Peru High in the Peruvian Andes, tucked away in a location unimaginable to most, lies Machu Picchu, the most famous archaeological site in the Americas. In 1911, while searching for Vilcabamba, the last Incan capital, American professor and explorer Hiram Bingham was led to the site by local indigenous farmers who had long known of its existence. Upon arrival, Bingham was stunned to discover a hidden village of Incan homes and temples, many overgrown with moss and encroaching vegetation. Perched 2,400 meters (7,900 feet) above sea level on a steep ridge, the site was crisscrossed by intricate stone terraces. Eager to share his findings, Bingham returned to the United States to publish his discovery, bringing global attention to Machu Picchu and organizing a formal excavation team. Today, the site has been extensively excavated and studied, and it ranks among the most visited archaeological destinations in the world. Experts believe Machu Picchu was built in the 15th century as a kind of summer retreat for the Incan elite. The site includes over 200 structures including homes, baths, and temples, divided into two main sections: the upper portion, primarily residential, and the lower, largely agricultural. These areas were separated by a large central square but connected by roughly 3,000 stone steps that allowed movement throughout the multi-tiered complex. Though likely a retreat for the elite, Machu Picchu is thought to have supported about 750 year-round residents, mainly composed of support staff and farmers. Despite its grandeur, the site remained unknown to the outside world for centuries. It is widely believed that the Spanish never discovered Machu Picchu, and it was largely forgotten after the collapse of the Inca Empire in the 16th century. However, this narrative overlooks the local indigenous communities, many likely descended from the Incas who dwelt at Machu Picchu, who continued to live nearby. In fact, Bingham himself was even surprised to encounter a family living close to the site during his ascent. ## Petra, Jordan In *Indiana Jones and the Last Crusade*, many viewers were introduced to their first glimpse of Petra, a real-life ancient city nestled in the desert of southern Jordan. Once the capital of the Nabataean Kingdom, Petra was intricately carved from the reddish sandstone cliffs of its surroundings in the 4th century BC, giving the city its iconic pink hue and the nickname "The Rose City." While the Treasury is undoubtedly the most recognizable structure, and often mistaken as the city's main entrance, Petra spans over 264 square kilometers (about 100 square miles), encompassing far more than just this famous façade. Petra was rich in temples, theaters, and other public buildings, many of which exhibit a striking blend of Hellenistic and Eastern architectural influences. Its location, strategically positioned between the Dead Sea and the Red Sea, allowed the Nabataeans to control a crucial trade route connecting Arabia, Syria, and Egypt. This access helped Petra flourish as a cultural and economic hub for centuries. Beyond trade, archaeological evidence suggests the Nabataeans also mined copper in the surrounding areas, further boosting the city's prosperity. At its peak in the 1st century AD, Petra is believed to have housed around 20,000 residents, as evidenced by the numerous rock-cut tombs and dwellings still visible today. One of Petra's most impressive features was its advanced water management system. Ingeniously engineered to support life in an arid desert climate, the system included tunnels, diversion dams, cisterns, and reservoirs that worked together to supply a stable water source for thousands of inhabitants. In the 2nd century AD, the Romans annexed Petra and redirected key trade routes, diminishing the city's economic importance. Despite this, Petra remained occupied, with the Romans, and later the Byzantines, adding their own structures, including several Christian churches. The city is thought to have been gradually abandoned by the 7th or 8th century AD. Though Petra faded from the world's attention, it was never entirely "lost." Bedul Bedouin communities continued to live near and within the ruins for centuries, often serving as the site's unofficial guardians. In 1812, Swiss explorer Johann Ludwig Burckhardt rediscovered Petra for the Western world. According to accounts, he gained access by disguising himself as a pilgrim and convinced the Bedouins to lead him to the site. When Petra was designated a UNESCO World Heritage Site in 1985, several Bedul families were still living within the ancient city, using its structures as homes and stables. As part of preservation efforts, the Jordanian government relocated these families to a nearby village, yet their legacy as caretakers of Petra remains deeply woven into the site's modern story. ## Sigiriya, Sri Lanka In the 5th century AD, Sri Lanka's Moriya dynasty found itself in a period of turmoil. After overthrowing his father and seizing the throne, King Kashyapa was locked in a civil war with his brother Mogallana, the rightful heir. To secure his position and prepare for war, Kashyapa decided to build a nearly impregnable fortress atop a 180-meter (600-foot) granite column, from which he could safely launch his military campaign. According to Buddhist texts, the site was already believed to have been used as a monastery, which Kashyapa believed helped frame his rule as righteous and divinely sanctioned. At the base of this towering rock, Kashyapa constructed a grand staircase with a mid-way landing guarded by a colossal brick-and-plaster lion. To continue climbing to the summit, visitors had to pass through the lion's mouth. Today, only the lion's massive paws remain, flanking the stairway, but they're enough to confirm the legendary structure was real. Climbing the 1,200 steps to the top, which are lined with galleries and terraces, visitors would arrive at a breathtaking sight. Sigiriya, as it came to be known, served as Kashyapa's capital and was transformed into a sophisticated citadel. The summit held the main palace complex, surrounded by smaller palaces, homes, terraced gardens, fountains, and even a moat. Inside the king's palace was a "mirror wall," which was polished so finely that Kashyapa could admire his reflection as he walked by. Nearby, a 140-meter (460-foot) long and 40-meter (131-foot) high wall once displayed vibrant frescoes of beautiful women, evidence of which survives through ancient graffiti left behind by early admirers. Sigiriya also featured an advanced hydraulic system, incorporating canals, dams, bridges, and underground pumps that distributed water throughout the gardens and fountains. Remarkably, this system was engineered so precisely that some fountains still operate during heavy rains, delighting modern visitors with the ingenuity of ancient Sri Lankan engineering. However, not long after Sigiriya's completion, Mogallana launched an attack. Kashyapa's army quickly abandoned him, and his wives leapt to their deaths from the rock's edge, rather than be taken alive. The fortress fell swiftly, and the king's mountaintop paradise was left behind. In the years that followed, Sigiriya became a Buddhist monastery, remaining active until the 14th century, and later served as a military outpost for the Kingdom of Kandy in the 16th and 17th centuries. So, when British Army Major Jonathan Forbes "discovered" the site in 1831 while horseback riding, and brought it to the wider world's attention, he was merely reintroducing a place that had never been truly forgotten, one remembered by locals and preserved in Buddhist texts for centuries. ## Mesa Verde, US While the United States is often overlooked in the search for lost cities, that doesn't mean it lacks any. Quite the opposite, in fact. Before the arrival of Europeans, millions of Native Americans were already living on the land. The U.S. government officially recognizes 574 different tribes today, though the true number was likely much higher. Many of these peoples built towns and cities, one of the most famous being Mesa Verde in southwestern Colorado. At Mesa Verde, more than 600 dwellings were discovered, built from sandstone and mud mortar, carved directly into the cliffs and alcoves of the surrounding canyon walls. This was home to the Ancestral Puebloan people for about 700 years, from around 550 AD to 1300 AD. Though the cliff dwellings are the most iconic feature of Mesa Verde, they represent only a small portion of the site's 4,700 archaeological features and were likely only constructed during the last 75 to 100 years of occupation. Structures across the site vary widely in size, from small storage rooms to large villas capable of housing between 50 to 200 people, some with as many as 150 individual rooms. Among the most famous buildings are the multi-story Cliff Palace, the Balcony House, and Tower Square. However, the site also contains countless pit houses, masonry towers, farming terraces, and field houses. Mesa Verde featured a sophisticated water management system, including check dams, ditches, and reservoirs, as well as numerous shrines and rock art, testament to a highly developed, domesticated culture, whose descendants, the modern Pueblo peoples, maintain many of these traditions today. At its peak, Mesa Verde likely supported thousands of residents, though exact numbers remain uncertain. In the late 13th century, the Ancestral Puebloans began migrating, primarily to nearby regions like modern-day New Mexico and Arizona, leaving the site uninhabited. It remained that way until 1888, when two cowboy brothers "rediscovered" the ancient city. Yet it was never truly forgotten. Local Indigenous groups, including the Pueblo, Navajo, and Ute peoples, preserved knowledge of Mesa Verde through oral traditions, passing down stories and legends that kept its memory alive. It's even likely that the site continued to be used intermittently over the following centuries, offering temporary refuge from the elements to those who remembered it. ## Angkor, Cambodia From the 9th to the 15th centuries, the Khmer people of Southeast Asia ruled a vast empire that encompassed much of present-day southern Vietnam, Laos, Thailand, and Cambodia. Cambodia served as the empire's heartland, with its now-famous capital, Angkor, located in the northern province of Siem Reap. While Angkor's fame is due in no small part to the stunning temple of Angkor Wat, the city itself offers an extraordinary glimpse into the grandeur and sophistication of the Khmer Empire. In addition to Angkor Wat, widely regarded as the largest religious site in the world, the city is home to numerous other temples, including Ta Prohm and Bayon. Many of these were originally dedicated to Hindu deities. However, as the empire gradually transitioned to Buddhism, Buddhist iconography became intertwined with Hindu symbolism, transforming the temples and the city into a unique and beautiful fusion of the two religions. Although the temples are what Angkor is best known for today, the ancient city was once a thriving metropolis. Archaeological evidence suggests that the population may have reached between 600,000 and 750,000 people, with remnants of residential areas still visible across the region. To sustain such a large population, the Khmer developed an extensive and sophisticated water-management system that included dykes, massive reservoirs, canals, basins, and an underground drainage network. To connect Angkor with the wider empire, they also built an impressive network of roads, complete with rest houses and stone bridges, much like the Roman infrastructure, linking the provinces back to the capital. Over time, the Khmer Empire shifted its capital, and years of warfare and gradual decline led to Angkor's eventual abandonment. In the 1860s, French explorer Henri Mouhot famously "rediscovered" the ruins. However, this narrative oversimplifies the reality. Angkor and its temples remained important pilgrimage sites for Khmer people, Buddhists, and Hindus alike. While parts of the city were indeed overtaken by jungle, Angkor was never truly lost. In fact, the area is still inhabited today, with nearby villages home to descendants of Angkor's original citizens who never left the region. ## Babylon, Iraq About 94 km (59 miles) southwest of Baghdad, Iraq, lies one of the most important, beloved, and frequently visited cities of the ancient world: Babylon. By the time of the Roman Empire, Babylon's architecture and cultural legacy were already so renowned that the city appeared in biblical texts, most famously in the story of the Tower of Babel, and its legendary Hanging Gardens were counted among the Seven Wonders of the Ancient World. Yet Babylon's history predates the Romans, the Bible, and many of the sources that shaped our modern understanding of it. Located along the lower Euphrates River in southern Mesopotamia, the city is believed to have existed before the reign of Sargon of Akkad (c. 2334–2279 BC), as references to Babylon appear in records from that time, though it likely began as a relatively minor port settlement. It wasn't until the reign of Hammurabi (c. 1792–1750 BC) that Babylon rose to prominence. Hammurabi established the city as the capital of his expanding Babylonian Empire, strengthening its defensive walls and initiating major public works, including temples and canals. Under his rule, Babylon grew rapidly, with its population estimated to have surpassed 100,000. After Hammurabi's death, the city fell to the Hittites, then to the Assyrians, and eventually to the Chaldeans, who would form the Neo-Babylonian Empire. During this era, especially under Nebuchadnezzar II, Babylon reached the height of its power and splendor. Some of its most iconic architectural achievements, such as the Ishtar Gate and the fabled Hanging Gardens, are attributed to this period. The population may have exceeded 200,000, marking the city's peak in both size and cultural influence. Eventually, however, the Neo-Babylonian Empire would also fall. In 539 BC, Babylon was conquered by Cyrus the Great who made it the seat of the Persian Achaemenid Empire. Later, in 331 BC, it was captured by Alexander the Great. As centuries passed and empires rose and fell, Babylon endured, until its eventual decline and abandonment, likely by the 7th century AD. Over time, it faded into ruin, buried by sand and time. In 1899, German archaeologist Robert Koldewey began formal excavations of the "lost" city, though European travelers had encountered the ruins for centuries prior, even if they didn't fully grasp their significance. Yet to locals, Babylon had never been lost. The nearby city of Hillah, located just 5 km (3.1 miles) to the south, has long stood in the shadow of its ancient predecessor. For countless generations, residents grew up with the ruins in plain sight. So, when the wider world began speaking of Babylon's "rediscovery," many locals were left puzzled because, for them, it had never truly been forgotten. ## Key Takeaways - Local communities preserved cultural memory of ancient cities like Petra and Machu Picchu. - Great Zimbabwe was a sophisticated city with extensive trade networks, contrary to European beliefs. - Machu Picchu was known to local indigenous communities long before Hiram Bingham's 'discovery'. - Petra's advanced water management system supported a large population in an arid desert climate. - Sigiriya's hydraulic system, engineered by King Kashyapa, still functions during heavy rains today. ## Frequently Asked Questions ### What is the significance of Great Zimbabwe?
