This is the mysterious megalithic city of Nan Madol. Located off the coast of Pohnpei Island in the Western Pacific Ocean, the dark, colossal basalt pillars of its ancient manmade islands rise from the emerald sea. Its remnants, an intricate labyrinth of enormous stones and waterways, capture stories of an ancient civilization lost in the tides of time.

This architectural marvel poses a confounding puzzle - how were these stone blocks, some weighing up to 50 tons, transported here off the coast amidst the crashing waves and coral reefs?

Considered to be inhabited by spirits according to local folklore, Nan Madol is rife with legends of sorcerers and flying dragons. This mysterious city, once the ceremonial and political hub of the Saudeleur Dynasty, now sits deserted, with few clues as to the fate of its inhabitants.

Who built this island marvel, and what secrets do its ruins tell?
