Knowed as Soun Nan-leng (Reef of Heaven), Nan Madol is located in the Federated States of Micronesia. The name Nan Madol means “spaces between” and is a reference to the canals that crisscross the ruins. Little can be verified about the megalithic construction.
Pohnpeian tradition claims that the builders of the Lelu complex on Kosrae (likewise composed of huge stone buildings) migrated to Pohnpei, where they used their skills and experience to build the even more impressive Nan Madol complex. However, this is unlikely: radiocarbon dating indicates that Nan Madol predates Lelu. Like Lelu, one major purpose of constructing a separate city was to insulate the nobility from the common people.
According to Pohnpeian legend, Nan Madol was constructed by twin sorcerers Olisihpa and Olosohpa from the mythical Western Katau, or Kanamwayso. The brothers arrived in a large canoe seeking a place to build an altar so that they could worship Nahnisohn Sahpw, the god of agriculture. After several false starts, the two brothers successfully built an altar off Temwen Island, where they performed their rituals. In legend, these brothers levitated the huge stones with the aid of a flying dragon.
