What it is

A ceremonial and political centre built on nearly a hundred artificial islets with basalt columns stacked in a criss-crossed log-cabin pattern. It is the largest megalithic work in Oceania and a feat of transporting stone by sea.

The megalithic construction is dated by uranium-thorium to c. 1180-1200, over earlier occupations.

What it led to

  • the centralised Saudeleur state on Pohnpei
  • the engineering of artificial islets over reefs
