Most Incredible Lost Cities

Throughout human history, countless civilizations have risen and fallen, leaving behind vast settlements, towns, and even sprawling cities, many of which have vanished entirely. Over time, these lost cities often faded into legend, remembered only through tales so fantastical that they were dismissed as mere myth. In other cases, cities lay abandoned for so long that they were forgotten altogether, only to be rediscovered centuries later by people unaware they had ever existed.

So, today, we’ll explore ten of these incredible lost cities. Note that this list excludes places like Machu Picchu and Petra since, while unknown to outsiders for a time, they were never truly lost, having remained in the memory and awareness of local communities.

With that said, let’s dive in.

Troy, Turkey

In Homer’s Iliad, Troy is portrayed as one of the great cities of the Bronze Age, famed for its walls, so formidable that they were said to have been built by the gods Poseidon and Apollo themselves. These divine fortifications would prove useful during the mythologized ten-year siege of the Trojan War, sparked when the Greeks set out to reclaim the beautiful Helen, who had been taken by Paris, prince of the city-state. Although Troy was once widely recognized in the ancient world as a real city, the events described in the Iliad are believed to have occurred sometime in the 13th century BC. Over time, the city was lost, and many came to see the entire tale as nothing more than a poetic invention of Homer’s imagination. That perception persisted until the late 19th century, when excavations at a site in Çanakkale, Turkey, reignited belief in the city’s historical foundation.

The first excavations were carried out by Frank Calvert in 1863, but it was the later work of Heinrich Schliemann, who excavated the site from 1870 to 1890, that truly brought Troy back into public awareness. Schliemann was convinced the site was the legendary city and was determined to prove it. What he uncovered was astonishing: nine distinct cities built one atop the other, representing at least 46 layers of habitation spanning thousands of years.

Convinced that the city of legend lay at the bottom, Schliemann infamously used dynamite to dig as deep as possible, showing little regard for the historical layers he destroyed in the process. His efforts were, in his view, vindicated when he uncovered gold and silver jewelry, storage vessels, and other artifacts, which he believed had belonged to the ancient Trojans. Unfortunately for Schliemann, later analysis revealed that these artifacts were roughly 1,000 years older than the events described in the Iliad and the site proved to be far older and more complex than he, or anyone else, had imagined possible.

Troy I, dating from 3000 to 2550 BC, was a small village surrounded by simple stone walls and little else. Troy II, which dates to around 2550–2250 BC, featured larger buildings with mudbrick and stone fortifications and imposing gates. Most of Heinrich Schliemann’s famous discoveries likely came from this level. Troy III through Troy V, 2250–1750 BC, meanwhile, have proven much more difficult to reconstruct.

These layers suffered significant damage or were carelessly destroyed during early excavations, making detailed study challenging.

However, Troy VI, dating from roughly 1750 to 1300 BC, stands out as one of the most impressive phases of the city’s history, and the level most often associated with the Troy of Homer’s Iliad. The city during this period was fortified with massive limestone walls up to 8 meters (26 feet) tall and 5 meters (16 feet) thick, reinforced by towers and accessed through five monumental gateways. Evidence from this layer also points to a thriving wool industry, a strong connection with horses, and a population likely numbering around 10,000. All consistent with Homer’s descriptions of a wealthy and powerful city. There is also archaeological evidence that Troy VI was violently destroyed, possibly by an earthquake or a siege and fire, mirroring the sack of Troy depicted in the Iliad.

Yet the story of Troy didn’t end with that destruction. Later layers reveal Greek and Roman buildings and artifacts, suggesting the city remained significant well into classical antiquity. Ultimately, it was likely the shifting coastline, cutting Troy off from its vital maritime trade routes, that led to its final decline and not the flames of mythic war.

Helike, Greece

As the second city in today’s list with ties to Greek myth, and spoiler alert, it won’t be the last, it should come as no surprise that many have questioned whether Helike was ever a real place. Allegedly founded during the Mycenaean period by Ion, leader of the Ionians, Helike would rise to become one of the most important cities of antiquity. According to Homer, it fought for the Greeks during the Trojan War and was so influential that it became the capital of the Twelve Cities of ancient Achaea and the head of the Achaean League.

Historical sources also describe Helike as one of the most significant religious sites in ancient Greece, second perhaps only to the Oracle at Delphi, thanks to its grand Temple of Poseidon. In addition, the city was reportedly a major cultural hub, minting its own coins and founding several colonies, including Sybaris, the most famous Greek city in southern Italy.

Eventually, myth tells us that Poseidon, enraged at the expulsion of the Ionians from Helike, submerged the entire city in a fit of divine wrath in 373 BC. An event which is often believed to have inspired the legend of Atlantis. For years, many in the Hellenic world, including the famed philosopher and mathematician Eratosthenes, visited the Gulf of Corinth in the northern Peloponnese, reporting sightings of a submerged city beneath the waves. Over time, however, these sightings faded, and Helike became yet another legendary cautionary tale about the consequences of angering the gods.

Of course, as is often the case with legendary cities, not everyone believed Helike to be mere myth. Many sought to uncover its remains, frequently searching in the Gulf of Corinth under the assumption that the city still lay submerged beneath the waves. But in 1988, archaeologist Dora Katsonopoulou and physicist Steven Soter launched the Helike Project, an initiative solely dedicated to finding the lost city. Over the next twelve years, the team conducted painstaking work, including underwater sonar scans, geological surveys, and drilling boreholes, all in hopes of locating Helike.

In 2001, they finally succeeded. Surprisingly, the city was discovered further inland than anyone had expected. This finding led to a major realization: for years, everyone had been looking in the wrong place.

Rather than being swallowed whole by the sea, as the myths suggested, Helike had actually been sunk by an earthquake, followed by a tsunami that likely washed over it. These natural disasters created a lagoon that submerged the city temporarily in antiquity. Over time, the lagoon dried up, leaving Helike buried beneath the coastal plains near the Gulf.

Following this breakthrough, the team began excavating the ancient city of legend. Helike itself proved impressive and its remains included buried buildings, city walls, pottery, coins, a large complex, and all the markers of a once-thriving Hellenic hub. Yet what truly astonished the researchers was what they found nearby: the remains of an Early Bronze Age town dating back roughly 2,000 years before Helike’s peak.

This earlier settlement revealed some of the best-preserved examples of Early Helladic architecture (c. 2600–2300 BC), complete with cobbled streets and signs of a flourishing community. Ironically, evidence suggested that this older town may have met a fate similar to Helike’s and it’s entirely possible that the Ionians themselves had myths about a once-great city nearby, destroyed by the wrath of the gods, long before their own was lost to the same forces.

Vilcabamba, Peru

Of all the lost civilizations throughout history, few have captured the hearts and imaginations of armchair archaeologists quite like those of Latin America, and it’s easy to see why. When Spanish conquistadors invaded Peru in 1532, it took less than 50 years for the Inca to fall from being the largest empire in pre-Columbian America to little more than a memory, along with their once-thriving cities and settlements. The Spanish invasion was swift and well-organized.

Shortly after their arrival, the Incan emperor Atahualpa was executed, and the capital city of Cusco fell. The remaining Inca were forced to flee in search of refuge. In 1539, they established a last stronghold in Vilcabamba, which became the capital of the Neo-Inca State and remained so until 1572.

By then, the Spanish had closed in. According to different accounts, the Inca either set fire to their city and escaped into the jungle or were overtaken by the conquistadors, who then destroyed Vilcabamba themselves.

For years, scholars believed Vilcabamba lay somewhere in the Cuzco region of Peru, but its exact location was lost to history. Hiram Bingham III, who famously brought Machu Picchu to international attention in 1911, believed he had discovered Vilcabamba and held firm to that belief until his death in 1956. Little did he know that Machu Picchu and Vilcabamba were entirely different sites, though he may have ground his teeth had he realized just how close he’d come.

Roughly 80 kilometers (50 miles) west of Machu Picchu, hidden beneath dense Amazon rainforest and nestled in the shadow of the Andes, lay the true Vilcabamba, untouched for centuries. Though some locals knew of the place, calling it Espíritu Pampa, or “Plain of the Spirits”, few, if any, grasped its true historical significance. That changed in 1964, when amateur archaeologist Gene Savoy identified the site, revealing its long-lost identity to the world.

The 15-hectare site was eventually excavated, a process that continues to this day, revealing an Incan settlement unlike any previously discovered. Among the findings were granite stone walls, residential buildings, agricultural terraces, cobbled streets, and temples. Many of these structures incorporated Spanish architectural elements, a unique feature of Vilcabamba that reflects the cultural collision of the era.

This blend is especially striking in the ceramic vessels found at the site, which depict Andean and Amazonian peoples fighting side by side, often aided by jaguars, against the conquistador invaders. As remarkable as these discoveries were, the most astonishing revelation came in 2010, when archaeologists unearthed artifacts linked to the Wari culture. Radiocarbon dating placed these items around 700 AD, suggesting the site had been occupied far earlier than previously believed.

The remnants of a Wari burial complex, temple, and various artifacts provided valuable insight into a civilization that predated the Inca by centuries, expanding our understanding of the region’s deep and layered history.

Thonis-Heracleion, Egypt

As promised, it’s time to return to Greek mythology for our next entry: Thonis-Heracleion. This was the place where Heracles is said to have first set foot in Africa. The site where Paris of Troy hid his beloved Helen from her husband, Menelaus, before the Trojan War. And, tragically, it became the setting for one of the greatest forgotten cities of the ancient world.

Located near modern-day Alexandria, at the mouth of the Nile River in today’s Aboukir Bay, Thonis-Heracleion was once a thriving Egyptian harbor city whose cultural, economic, and religious importance was almost unmatched in its time. Founded in the 8th century BC, the city flourished for more than 1,600 years, until it mysteriously vanished around the 8th century AD. As Egypt’s primary port, at least until the rise of Alexandria, it was a hub known to virtually everyone in the Mediterranean world.

Yet, despite its significance, its disappearance, likely caused by the clay soil underneath the city succumbing to liquification after experiencing natural disasters, led to the world essentially forgetting about the city for over 1,000 years. That changed in the late 1990s, when a team from the European Institute for Underwater Archaeology was drawn to the area while investigating the wrecks of 18th-century French warships. Using advanced survey equipment and a skilled team of divers, they began mapping the underwater topography of the region.

What they found was far beyond their original mission. A series of unexpected discoveries redirected their focus entirely toward the excavation of the long-lost city of Thonis-Heracleion.

Initially, the diving team began uncovering fragments of ancient statues, pottery shards, and jewels. Meanwhile, their survey equipment started detecting large underwater structures scattered across the bay. As the dives continued, they discovered the remains of a sunken temple, an ancient stele detailing tax laws, submerged buildings, and other monumental remnants of a once-thriving city, remarkably preserved. It soon became clear just how significant their discovery truly was.

For years, ancient texts had led scholars to believe that Thonis and Heracleion were two entirely separate cities, one Egyptian, the other Greek. But this site told a different story: it was a remarkable fusion of both cultures. Beneath the water, Hellenic and Egyptian helmets lay side by side with Athenian perfume bottles, anchors from Greek ships, Cypriot statuettes, and countless other artifacts from both civilizations.

Perhaps the most symbolic find was a figurine of Cleopatra III, who herself was an Egyptian queen of the Greek Ptolemaic dynasty, depicted as the goddess Isis, yet carved with distinctly Hellenic features. It was the perfect embodiment of the cultural blending at the heart of this city. In the end, the site didn’t just offer insight into daily life, it rewrote history.

It revealed that Thonis and Heracleion weren’t two cities, separated geographically and culturally, but one thriving metropolis that combined the two cultures and whose very name was simply dependent on whether you were asking a Greek or an Egyptian.

Atlit Yam, Israel

In the 1960s, numerous submerged settlements and shipwrecks began to be discovered off Israel’s Carmel Coast along the Mediterranean. In response, marine archaeologist Ehud Galili launched a research project aimed at locating, excavating, and preserving these lost villages and artifacts. Since then, 17 submerged prehistoric sites have been uncovered, all dating back thousands of years and offering valuable insights into humanity’s transition from a nomadic existence to urban life.

Among these remarkable discoveries, the most extensive and awe-inspiring is undoubtedly Atlit Yam, which Galili discovered in 1984. While some archaeological sites challenge our understanding of history, Atlit Yam has helped shape it, virtually writing the book on pre-pottery cultures and early human development in the region. Covering approximately 40,000 square meters (431,000 square feet), Atlit Yam is not only one of the largest submerged settlements ever found but also one of the oldest, dating back roughly 9,000 years, to the 7th millennium BC. Located 8 to 12 meters (26 to 39 feet) below sea level and about 200 to 400 meters (656 to 1,312 feet) offshore, the site provides an extraordinarily detailed glimpse into the daily lives of a prehistoric people, predating Stonehenge by nearly 4,000 years.

Despite this gap though, Atlit Yam was also home to a remarkable stone semi-circle composed of large monoliths, which experts believe may have served a spiritual or ritualistic purpose. Even more striking are the rectangular wall foundations of ancient homes found at the site. These structures contained central hearths and circular installations, likely used for food storage.

The village also featured an impressive well, 1.5 meters (5 feet) wide and 5.5 meters (18 feet) deep, with dry-stone interior walling, suggesting it was built for communal use. Artifacts uncovered at Atlit Yam include projectile points, axes, fishhooks, and other tools crafted from stone and animal bone, pointing to a strong fishing culture. However, evidence of farming has also been discovered, including remains of various plant species and signs of cattle domestication, confirming that the community practiced agriculture as well.

One of the most remarkable discoveries at the site came from intentional burial grounds, where archaeologists identified the world’s oldest known cases of tuberculosis. While Atlit Yam may not be as widely known or mythologized as other “lost cities,” it remains one of the most extraordinary. It offers a rare and vivid glimpse into the daily life of a Neolithic community, reminding us that long before the rise of cities as we know them, people were already living in organized, complex settlements.

Pompeii, Italy

Of all the lost cities discussed today, none are as well-known, thoroughly excavated, or historically informative as Pompeii, the most famous archaeological site in the world. Originally founded during the Bronze Age by Greek and Etruscan settlers, Pompeii is best known as a thriving Roman town near modern-day Naples. Although it now lies about 2 kilometers (1.2 miles) inland, Pompeii was much closer to the sea in antiquity.

The Romans were so enamored with the location that they transformed it into a bustling resort town on the Mediterranean, pouring resources into regular building projects throughout the 2nd century BCE. As a result of this rapid development, Pompeii reached its peak, growing into a vibrant city with densely populated suburbs and an estimated population of 10,000 to 20,000 people, with double that number found in the surrounding farms and villas.

In 79 CE, however, Pompeii was famously buried under volcanic ash following the eruption of Mount Vesuvius, an event whose exact date remains a topic of scholarly debate. While the city was never entirely lost to memory, its precise location was forgotten for more than 1,500 years, until locals rediscovered it in the late 16th century. Official excavations began in 1748 and are widely considered the beginning of modern archaeology as a scientific discipline. Since then, excavation efforts have continued almost without interruption, paused only by major events such as world wars or natural disasters, and they remain ongoing to this day.

While the volcanic eruption was a tragedy for the people of Pompeii, it proved invaluable to researchers centuries later. The layers of volcanic ash acted as a protective shield, preserving the city almost exactly as it was on that fateful day. Thousands of structures remain standing, including shops, taverns, temples, public baths and latrines, schools, and homes ranging from modest dwellings to sprawling villas that would put modern mansions to shame.

Many of these upscale villas feature large atriums with rectangular pools, private gardens, and intricate floor mosaics depicting everything from mythological scenes to the homeowner’s business ventures. Meanwhile, the city’s artifacts, written records, and even graffiti have offered extraordinary insight into everyday life in Pompeii, from trade and commerce to the crude humor that ancient Romans found amusing.

One of Pompeii’s most iconic and haunting features is the collection of plaster casts made from the voids left in the ash where victims’ bodies once lay. By carefully pouring plaster into these cavities, archaeologists were able to create detailed impressions of those who perished—often shown frozen in their final moments, curled up or crying out. These casts offer a powerful and humanizing glimpse into the catastrophe, unlike anything else in the archaeological record.

Perhaps most astonishing of all is that Pompeii has not yet been fully excavated and new discoveries continue to be made regularly. In early 2025, archaeologists uncovered an entire city block including a laundry, a bakery, and a grand private residence. Yet remarkably, nearly one-third of the ancient city still remains buried, waiting to be explored.

Mohenjo-Daro, Pakistan

During the Bronze Age, a few cultural powerhouses dominated large regions of the world and helped shape the societies that followed. Among them were the Minoans, the Hittites, the Mycenaeans, and others, many of whom remain mysterious to us today, either due to a scarcity of historical artifacts or because their writing systems have yet to be fully deciphered. Yet, among these enigmatic Bronze Age civilizations, few were as regionally dominant, long-lasting, or puzzling as the Indus Valley Civilization, also known as the Harappans.

At their height, the Harappans ruled an area stretching from present-day northeastern Afghanistan to northwestern India. They began building urban centers around 3300 BC and remained a significant presence in the region until approximately 1300 BC, making them the world’s earliest known urban culture.

Despite their widespread influence, only two major cities have been uncovered to date: Harappa and Mohenjo-Daro. The latter is located on the right bank of the Indus River, about 30 kilometers (19 miles) south of Larkana in southern Pakistan. Mohenjo-Daro was founded around 2600 BC and thrived for roughly 700 years before being abandoned around 1900 BC, likely due to climate change and flooding that made agriculture increasingly unsustainable.

Over time, the site was naturally buried under layers of sediment and soil, and both the city and its civilization faded from memory. It wasn’t until 1922 that R.D. Banerji, an archaeologist with the Archaeological Survey of India, rediscovered the site while investigating earlier reports of an ancient Buddhist stupa in the area.

His findings revealed the remains of one of the earliest known examples of sophisticated urban planning, matched only by its sister city, Harappa, which was founded around the same time.

At the heart of Mohenjo-Daro lies a fortified acropolis, once protected by ramparts and encircled by the lower town. This lower town is notable for its red mud-brick buildings, laid out in a carefully planned grid pattern with narrow streets and precise 90-degree angles. Walking through these ancient streets today, one can still see the remnants of multi-story homes, their archways strikingly similar to modern doorways.

Scattered throughout the city are the remains of public baths, wells, a massive granary, communal pools with wide staircases, soak pits for sewage disposal, and even a sophisticated street drainage system designed to prevent flooding. One of the most remarkable features, however, is the presence of private toilets in many homes, including those likely occupied by common citizens, demonstrating an advanced understanding of sanitation for the time.

Based on the culture that founded Mohenjo-Daro, it’s also believed to have been a major economic center. The city produced intricately carved pottery, figurines, jewelry, and other artifacts, many of which have been found across Mesopotamia and the modern-day Middle East. This suggests Mohenjo-Daro was not just a cultural center but also a vital trading hub of the Bronze Age.

Despite the discovery of numerous inscriptions at the site, the language, known as the Indus Valley Script, remains undeciphered. This pictographic script, composed of over 400 unique symbols, continues to puzzle scholars and leaves much of the civilization’s story untold. What is known, however, is that Mohenjo-Daro was one of the largest cities of the Bronze Age, likely home to more than 40,000 residents at its peak.

Its architectural ingenuity, urban planning, and preserved artifacts, such as decorative seals, sculptures, and the city itself, stand as lasting evidence of the sophistication and greatness of the Indus Valley Civilization.
