00:00So, let's start.
00:01Number 10, Heliki, the Greek city swallowed by the sea.
00:05For centuries, Heliki was remembered as one of the great cities of ancient Greece.
00:10It stood on the Gulf of Corinth, and was important enough to have its own sanctuary dedicated
00:15to Poseidon, the god of the sea, and earthquakes.
00:19Then in 373 BC, the city seemingly vanished.
00:24Ancient writers described a catastrophic earthquake followed by a tsunami that destroyed the city
00:29and covered the remains with water and sediment.
00:32The disaster became so famous that, later, Greek and Roman writers continued discussing
00:37the city's disappearance long after it happened.
00:39Over time, however, the exact location was forgotten.
00:42That created a fascinating archaeological problem.
00:46People knew the city had existed, but nobody could agree exactly where its remains were.
00:51Some searches focused on the sea, based on ancient descriptions that suggested it had
00:56been submerged.
00:57Other researchers believed the ruins might have been buried inland by changes in the coastline.
01:02The breakthrough came in the early 2000s.
01:05Archaeologists working in the delta discovered buried structures and archaeological layers associated
01:10with the ancient settlement.
01:12Excavations revealed buildings and artifacts beneath layers of sediment, helping researchers
01:17connect the remains to the city described by ancient writers.
01:21There is an important complication, however.
01:23However, modern geological research has questioned some traditional details of the destruction story,
01:29particularly the idea that the entire city simply disappeared beneath the sea.
01:34Archaeological evidence indicates that parts of the ancient settlement survived or existed
01:38on land, while earthquake, tsunami, sedimentation, and later environmental changes all affected the area.
01:44That makes this ancient city even more interesting.
01:47Its disappearance wasn't a simple case of a city sinking into the ocean.
01:51It was a combination of natural disasters and landscape changes that gradually concealed an important
01:57Greek settlement from view.
01:58Number 9, Shar-i Sokta.
02:00The ancient city known as the Burnt City.
02:03Thousands of years ago, a large city stood on the edge of the Iranian plateau in what is now southeastern
02:10Iran.
02:10Its name was Shar-i Sokta, which translates roughly to Burnt City.
02:16And at its height, it was part of a network of Bronze Age trade routes stretching across a huge region.
02:21The city was founded around 3200 BC and remained occupied for roughly 15 centuries.
02:27Archaeologists have identified separate residential, industrial, monumental, and burial areas,
02:33revealing a surprisingly organized urban society.
02:37The site has also produced an enormous collection of artifacts
02:40that provide clues about how its inhabitants lived, worked, traded, and died.
02:45What makes Shar-i Sokta particularly fascinating
02:48is how advanced some of its inhabitants appear to have been.
02:52Archaeologists have uncovered evidence of long-distance trade and specialized manufacturing,
02:57along with objects that reveal sophisticated craftsmanship.
03:00The city's location placed it along important routes connecting communities across the Iranian plateau and beyond.
03:06Then, the city was abandoned.
03:08There wasn't a single dramatic event that can be confidently blamed for its disappearance.
03:13UNESCO notes that changes in watercourses and climate played a role in the eventual abandonment of the city during the
03:20early 2nd millennium BC.
03:22As the environment around the settlement changed,
03:24the conditions that had supported such a large population became increasingly difficult.
03:29Afterward, the remains were gradually buried beneath the dry landscape.
03:33The desert climate helped preserve buildings, graves, and countless objects,
03:38leaving archaeologists with an unusually detailed record of Bronze Age urban life.
03:43Today, the ruins cover a vast area,
03:45but for thousands of years,
03:48Shar-i Sokta was effectively forgotten outside the local landscape.
03:52Excavations have since revealed a city that was far more complex than its remote location might suggest,
03:58providing a remarkable look into one of the earliest urban societies in eastern Iran.
04:04Number 8.
04:05Chan Chan
04:06The ancient city abandoned in the Peruvian desert.
04:10In the coastal desert of northern Peru,
04:12an enormous city once covered an area so large that its remains stretch across the landscape for miles.
04:18This was Chan Chan, the capital of the Chimu Kingdom,
04:22and one of the greatest cities of pre-Columbian South America.
04:25At its height during the 15th century, Chan Chan contained enormous compounds surrounded by high adobe walls.
04:32The city was carefully organized into separate areas,
04:35including nine major citadels or palace complexes.
04:39Inside were plazas, ceremonial spaces, residences, storage areas,
04:44workshops, and sophisticated systems for managing water and agriculture.
04:49The scale is difficult to imagine because the entire city was constructed primarily from earth and mud brick.
04:56Instead of stone monuments like those found in many ancient civilizations,
05:00Chan Chan's architecture depended on enormous quantities of adobe.
05:04Walls were decorated with geometric patterns, animals, birds,
05:08and other designs that revealed aspects of Chimu culture.
05:12The city also depended on an elaborate system of canals and agricultural infrastructure.
05:17Engineers redirected water through the surrounding landscape,
05:20allowing the population to support a major urban center in one of the driest regions on earth.
05:25UNESCO describes Chan Chan as the largest earthen architecture city in pre-Columbian America,
05:31but Chan Chan's independence eventually came to an end.
05:34In the 15th century, the expanding Inca Empire conquered the Chimu Kingdom
05:38and incorporated its territory into the Inca state.
05:42The city continued to exist afterward,
05:44but its political importance declined dramatically.
05:48Over the following centuries,
05:49the enormous urban complex was gradually abandoned
05:52and exposed to the harsh desert environment.
05:55Today, Chan Chan is an archaeological zone rather than a living city,
05:59with its enormous walls and palace compounds providing a glimpse into a civilization
06:04that once controlled a large part of Peru's northern coast.
06:08Much of the original city is gone,
06:10but enough survives to reveal just how enormous and organized Chan Chan once was.
06:16Number seven, Akrotiri, the Minoan city buried by a volcanic eruption.
06:20Long before Santorini became one of Greece's most famous tourist destinations,
06:24a sophisticated Bronze Age settlement stood on the island.
06:27Its inhabitants lived in multi-story buildings, used advanced drainage systems,
06:31produced elaborate pottery, and decorated their walls with colorful frescoes.
06:36The settlement is now known as Akrotiri.
06:39Around the middle of the second millennium BC,
06:42one of the largest volcanic eruptions in human history transformed the island.
06:47The enormous Theron eruption sent ash and volcanic material across the region,
06:52while earthquakes and other geological activity affected the settlement
06:55before and during the disaster.
06:57Akrotiri was eventually buried beneath layers of volcanic material.
07:02That destruction created an extraordinary archaeological time capsule
07:06because the settlement was covered by volcanic deposits,
07:09buildings, furniture, pottery, and wall paintings survived in remarkable condition.
07:14UNESCO describes the site as
07:16a Minoan Bronze Age settlement associated with the civilization that flourished across the Aegean.
07:22The buildings discovered there reveal a level of urban organization
07:25that can be surprising to anyone expecting Bronze Age settlements to consist mainly of simple houses.
07:31Some structures reached several stories,
07:33while sophisticated drainage systems ran through the town.
07:36Frescoes depict ships, landscapes, animals, plants, and people,
07:40offering archaeologists clues about the world these inhabitants knew.
07:45One of the strangest aspects of Akrotiri
07:47is the apparent lack of human remains of the site.
07:49Archaeologists have found evidence that residents may have evacuated
07:52before the largest stages of the eruption.
07:55Earlier earthquakes may have given them enough warning to leave,
07:58although exactly how many people escaped and where they went remains uncertain.
08:02For centuries, Akrotiri was hidden beneath volcanic deposits.
08:05When archaeologists eventually began excavating it,
08:09they uncovered streets, houses, artwork,
08:11and everyday objects that had remained sealed away for thousands of years.
08:15The result is one of the clearest archaeological windows into Bronze Age life anywhere in the Aegean.
08:22Number 6.
08:23Ani, the medieval city, left empty on the Armenian frontier.
08:29On a remote plateau near the modern border between Turkey and Armenia
08:33stand the ruins of a city that once rivaled the great urban centers of the medieval world.
08:39This was Ani, a major Armenian capital that became one of the most important cities
08:44along the Silk Roads.
08:45Ani flourished particularly during the 10th and 11th centuries
08:49when it became the capital of the Bagratid Armenian Kingdom.
08:53Its position gave it access to major trade routes
08:56and merchants traveling between Byzantium, Persia, Syria, and Central Asia
09:01passed through the region.
09:02The city grew into a dense urban center
09:05filled with churches, palaces, fortifications, markets, houses, and other structures.
09:10Its architecture also reflected the different cultures that passed through the city.
09:15Armenian Christian buildings stood alongside structures influenced by Byzantine,
09:20Seljuk, Georgian, and Islamic traditions.
09:23Then, Ani's fortunes began to change.
09:26The city experienced political upheaval, invasions, and a devastating earthquake in 1319.
09:33Trade routes also shifted, reducing the economic importance that had helped Ani flourish for centuries.
09:39The Mongol invasion added another major blow to the city's decline.
09:44Ani survived in a diminished form for centuries,
09:46but its population gradually disappeared.
09:49By the 18th century, it was largely abandoned.
09:52What makes the ruins especially striking today
09:54is how much of the medieval city remains visible.
09:57Massive walls still cross the plateau
09:59while churches and other buildings rise from the otherwise empty landscape.
10:04Underground tunnels and caves also exist beneath parts of the site.
10:07For centuries, the abandoned city sat in an isolated border region
10:11far removed from the urban world that had once made it wealthy and powerful.
10:16Its ruins eventually became a major archaeological site,
10:20preserving an unusual record of medieval life at the crossroads of several civilizations.
10:25Number 5, Cahokia.
10:27The enormous ancient city that was abandoned in North America.
10:31Long before European explorers arrived in North America,
10:35a huge urban center was growing beside the Mississippi River near what is now St. Louis.
10:41This was Cahokia, a city built by indigenous peoples that eventually became the largest known
10:46pre-Columbian settlement north of Mexico.
10:49At its height around the 11th and 12th centuries, Cahokia covered a vast area containing thousands of buildings,
10:56enormous plazas, residential neighborhoods, and dozens of massive earthen mounds.
11:02The largest, Monk's Mound, rises roughly 30 meters above the surrounding landscape
11:08and covers more than 14 acres at its base.
11:11The city was carefully planned.
11:13Some plazas were enormous open spaces that could accommodate large gatherings
11:18while the surrounding mounds served different ceremonial, political, and residential purposes.
11:25Archaeologists have also found evidence of long-distance trade,
11:29with materials originating hundreds of kilometers away.
11:32Then, sometime after reaching its peak, Cahokia began to decline.
11:37The exact reasons remain debated.
11:39Researchers have proposed combinations of environmental changes, flooding, deforestation,
11:45social or political instability, and changes in regional climate.
11:49There was probably no single event that suddenly emptied the city.
11:53By the 14th century, Cahokia had largely been abandoned as a major urban center.
11:59Its enormous mounds remained visible across the landscape,
12:02but the civilization that had built them was no longer there.
12:05Later, European settlers encountered some of the earthworks,
12:09but they did not initially understand the true scale or age of the settlement.
12:14Some mounds were eventually destroyed by farming, roads, and modern development
12:19before archaeologists could properly document them.
12:22Today, the remaining site provides evidence of an extraordinarily complex society
12:28that developed entirely within North America.
12:31Cahokia's existence challenges older assumptions about the size and organization
12:36of indigenous settlements before European colonization,
12:40revealing a major urban center that had already disappeared centuries earlier.
12:45Number 4. Timgad, the Roman city buried beneath the Algerian sands.
12:51In the mountains of northern Algeria,
12:53the remains of a Roman city sit remarkably preserved beneath the landscape.
12:58Its name was Timgad, and it was founded by the Roman emperor Trajan around 100 AD,
13:05as a military colony.
13:06The city was designed with an unusually precise grid.
13:10Streets crossed one another at right angles,
13:13creating a pattern that reflected Roman urban planning.
13:16At its height, Timgad contained houses, public baths,
13:20a forum, a theater, temples, markets, and a library.
13:24One surviving inscription from the city famously describes
13:28the pleasure of having a bath, a drink, and a game.
13:31The words provide a surprisingly personal glimpse into ordinary Roman life,
13:36while the remains of the buildings reveal
13:37how extensively Roman culture had spread into North Africa.
13:41Timgad remained inhabited for centuries,
13:43and eventually became an important Christian center,
13:46but political instability, economic changes,
13:48and invasions gradually weakened the city.
13:51By the early medieval period, the settlement had largely been abandoned.
13:55The surrounding landscape then helped preserve what remained.
13:58As the city emptied, windblown sand and soil gradually covered sections of the streets and buildings.
14:04This helped protect parts of Timgad from later development,
14:07and left archaeologists with an unusually complete Roman urban layout.
14:12When systematic excavations began in the 19th century,
14:15archaeologists uncovered an entire Roman city emerging from the ground.
14:19Streets, arches, houses, public buildings, and monumental structures
14:23appeared almost as though the population had vanished only recently.
14:27Today, Timgad is one of the best preserved examples of Roman town planning in North Africa.
14:33Its ruins show how a city built on the edge of the Roman Empire
14:37could develop into a sophisticated urban center,
14:40only to become deserted and eventually disappear beneath the landscape for centuries.
14:44Number 3, Heracleion, the Egyptian port that disappeared beneath the Mediterranean.
14:51For centuries, Heracleion was almost treated like a lost legend.
14:55Ancient writers described an important Egyptian port called Thaunus, known to the Greeks as Heracleion,
15:01located near the mouth of the Nile.
15:03But as centuries passed, the city disappeared from the landscape.
15:07Eventually, its location became uncertain.
15:09Heracleion had once been a major commercial gateway into Egypt.
15:13Ships arriving from across the Mediterranean passed through its waterways
15:17while merchants traded goods from different parts of the ancient world.
15:20The city also contained temples dedicated to Egyptian gods,
15:24including a major sanctuary associated with a moon.
15:27Then, the landscape beneath the city began to change.
15:30The region was naturally vulnerable to earthquakes,
15:33rising sea levels, and the gradual instability of the Nile Delta.
15:38Over time, parts of the city sank and were covered by sediment.
15:41Eventually, Heracleion was submerged beneath the Mediterranean.
15:45For centuries, the city remained hidden underwater.
15:48That changed in the early 2000s when underwater archaeologists led by Frank Goddio
15:53located extensive ruins in Abu-Kirbay.
15:56What they discovered was extraordinary.
15:59Statues, inscriptions, coins, jewelry, architectural fragments,
16:02and enormous stone structures were found scattered across the seabed.
16:06Among the discoveries were colossal statues representing Egyptian deities,
16:11and members of the Ptolemaic royal family.
16:14Archaeologists also found evidence of the city's role as a busy port,
16:18including anchors and remains associated with ancient ships.
16:22The discoveries confirmed that the city described by ancient writers
16:26had been a real and substantial urban center.
16:29Its disappearance had not been a literary invention.
16:32Instead, Heracleion had gradually become buried beneath the changing landscape of the Nile Delta
16:38and eventually submerged beneath the sea.
16:41Today, its ruins remain underwater where archaeologists continue to study the remains of a city
16:47that disappeared from the surface world for more than a thousand years.
16:52Number two, Mahendra Parvada, the lost Khmer city, hidden in the Cambodian jungle.
16:58Deep in the Cambodian jungle, archaeologists discovered evidence of a huge ancient urban landscape
17:03that had been hidden beneath dense vegetation for centuries.
17:06The site is known as Mahendra Parvada, an early Khmer settlement located on Hnam Kulen.
17:13The city dates to the 9th century and is associated with King Jayavarman II,
17:17who played a crucial role in the formation of the Khmer Empire.
17:21For a long time, researchers knew that important Khmer sites existed in the area,
17:26but understanding their true size and organization was extremely difficult
17:30because the jungle concealed much of the ancient landscape.
17:34Then, airborne laser scanning changed the picture.
17:37Using LiDAR technology, researchers were able to see through the forest canopy
17:42and identify structures that were almost impossible to detect from the ground.
17:47Roads, reservoirs, temples, embankments, and other features appeared in the data,
17:51revealing a much more extensive urban network than archaeologists had previously recognized.
17:57The discovery changed how researchers understood the early development of Khmer cities.
18:02Rather than being a collection of isolated temples hidden in the jungle,
18:06Mahendra Parvada appears to have been part of a large planned landscape
18:09with infrastructure connecting different areas.
18:12Over time, the political and economic center of the Khmer Empire shifted toward the Angkor region.
18:18Mahendra Parvada eventually declined, leaving behind structures that were gradually swallowed by vegetation.
18:25The jungle effectively concealed much of the city's layout,
18:28until modern technology allowed researchers to map the terrain from above.
18:32Mahendra Parvada is therefore unusual among lost cities because archaeologists knew parts of the ancient landscape existed,
18:39but LiDAR revealed just how extensive the settlement actually was.
18:43Beneath the trees was a complex urban system that had remained difficult to see for generations.
18:49Number one, Ciudad Perdida, the forgotten city, hidden deep in the Colombian mountains.
18:56High in the Sierra Nevada de Santa Marta mountains of Colombia,
19:00lies an ancient city that was hidden beneath dense vegetation for centuries.
19:04Known today as Ciudad Perdida, or the Lost City, it was built by the Tairona civilization long before the arrival
19:13of the Spanish.
19:14The settlement is generally dated to around the 9th century, making it older than the Inca citadel of Machu Picchu.
19:22It was constructed on steep mountain terrain, with stone terraces, stairways, plazas, and platforms built into the landscape.
19:30Getting there is difficult even today. The site can only be reached by traveling through mountainous terrain and following a
19:37long trail through the rainforest.
19:39The ancient inhabitants had to solve the same geographical problem on an even larger scale, constructing an urban settlement across
19:46extremely steep slopes.
19:48The city appears to have been an important political and cultural center within the surrounding region.
19:54Hundreds of stone terraces were connected by an extensive network of paths and stairways, while drainage systems helped control the
20:02heavy rainfall that regularly hits the mountains.
20:06After the Spanish conquest, the settlement was eventually abandoned.
20:10The jungle gradually covered the structures, and for centuries the city was largely unknown to the outside world.
20:16Modern interest in Ciudad Perdida grew dramatically during the 1970s, when archaeologists began systematic investigations of the site.
20:26Excavations revealed a much larger and more sophisticated settlement than outsiders had expected, with dozens of terraces and structures spread
20:34across the mountains.
20:35Colombia's Archaeological Institute identifies the site as Teyuna, one of the country's major archaeological parks.
20:43Today, the ruins can be reached by trekking through the same mountains that once protected the city from outsiders.
20:51Stone stairways still climb through the forest, connecting terraces that were built centuries ago.
20:57The jungle concealed Ciudad Perdida for generations, but the surviving architecture reveals a remarkable mountain city that was carefully engineered
21:06for one of the most challenging environments in South America.
