“Between 1200 and 1500 CE, Pohnpei islanders used basalt and coral boulders to build over 100 islets off the coast of the main island. The size and sophistication of these artificial isles and the structures they host are a record of the achievements and culture of Saudeleur dynasty Pacific Island peoples. Stone palaces, temples, tombs, and homes once lined this 200-acre ‘city on water.’

The thing about a city on the water is that it is extremely vulnerable to the elements. The site is unmodified by modern human hands but has been unused since the 1820s. Rampant plant life undermines Nan Madol’s structure, while storm damage continues to compromise the stonework.”
