Ancient Lost Cities: History of Dunwich, Heracleion, Ciudad Perdida, Nan Madol

Here are four more stories of lost cities from the past, that will take us around the world and from Antiquity to our days:

- Dunwich (UK) was a thriving medieval city that grew during the Anglo-Saxon period on the North Sea coast, and peaked in the 14th century. But centuries of coastal erosion led to the disappearance of most of its buildings and houses.

- Heracleion was Egypt's most active port during the Late Period of Ancient Egypt. However, rising waters and soil liquefaction condemned it and its ruins remained forgotten and undisturbed for centuries, several miles off the coast and under 19 feet of water, until its recent rediscovery.

- Ciudad Perdida (Colombia) was a spectacular city built in the mountains of Colombia by the Tairona, with dozens of terraces connected by staircases and pathways.

- Nan Madol (Micronesia) was the capital of the Saudeleur dynasty in Pohnpei. Sometimes called the ""Venice of the Pacific"", it consisted of more than 90 artificial islets and megalithic architecture.
