The core of the ritual and residential area was the seat of Pohnpei's ruling Sau Deleur dynasty in prehistoric times. Development of the island's "chief" hierarchy, one of the most complex in the Pacific islands, can be researched through archeological evidence here, such as the megalithic structures. The site thus provides opportunities for inquiry into the origins of complex societies. - NRHP Registration, 16 September 1985
