Nan Madol: A Glimpse into the Ancient Pacific Island Civilization

The Nan Madol, located off the southeast coast of Pohnpei, is a remarkable testament to the rich cultural heritage of Eastern Micronesia. Inscribed as a UNESCO World Heritage Site in 2016, this ceremonial center offers a unique insight into the vibrant period of Pacific Island civilization that thrived between 1200 and 1500 CE.

UNESCO Description of the World Heritage Site

Nan Madol is a series of more than 100 islets off the south-east coast of Pohnpei that were constructed with walls of basalt and coral boulders. These islets harbour the remains of stone palaces, temples, tombs and residential domains built between 1200 and 1500 CE. These ruins represent the ceremonial centre of the Saudeleur dynasty, a vibrant period in Pacific Island culture. The huge scale of the edifices, their technical sophistication and the concentration of megalithic structures bear testimony to complex social and religious practices of the island societies of the period. The site was also inscribed on the List of World Heritage in Danger due to threats, notably the siltation of waterways that is contributing to the unchecked growth of mangroves and undermining existing edifices.

Encyclopedia Record: Nan Madol

Nan Madol is an archaeological site adjacent to the eastern shore of the island of Pohnpei, now part of the Madolenihmw district of Pohnpei state in the Federated States of Micronesia in the western Pacific Ocean. Nan Madol was the capital of the Saudeleur dynasty until about 1628. The city, constructed in a lagoon, consists of a series of small artificial islands linked by a network of canals. The site core with its stone walls encloses an area approximately 1.5 by 0.5 kilometres and it contains 92 artificial islets—stone and coral fill platforms—bordered by tidal canals.
