Nan Madol: A Stone-Built Center in the Pacific Islands
Communities along the coast of Pohnpei transported basalt to build artificial islands and ceremonial structures, revealing complex political and religious organization in Micronesia.

The story
Around 1200–1500, the Nan Madol complex of more than one hundred small islands developed along Pohnpei's southeastern coast, serving as an important ceremonial center during Saudeleur rule. Local people transported columnar basalt from other locations on the island, using stone walls and coral blocks to construct island foundations, palaces, tombs, and residential areas. The scale and craftsmanship of the buildings show that Pacific island societies had complex practices of resource mobilization, hierarchy, and belief. Their history is also preserved in local oral traditions. Large stone-built sites cannot be explained as the work of an unknown foreign civilization, and the absence of written archives is no reason to disregard islanders' own knowledge.
Elsewhere in the world
The building of Nan Madol broadly coincided with Angkor and the expansion of Eurasian trade networks, showing that large political and ceremonial projects developed independently in several regions.
