Nan Madol - Archaeology and Tourism

Archaeology and Tourism

Today Nan Madol forms an archaeological district covering more than 18 km² and includes the stone architecture built up on a coral reef flat along the shore of Temwen Island, several other artificial islets, and the adjacent Pohnpei main island coastline. The site core with its stone walls encloses an area approximately 1.5 km long by 0.5 km wide and it contains nearly 100 artificial islets—stone and coral fill platforms—bordered by tidal canals.

Carbon dating indicates that the construction of Nan Madol began around AD 1200, while excavations show that the area may have been occupied as early as 200 BC. Some probable quarry sites around the island have been identified, but the exact origin of the stones of Nan Madol is yet undetermined. None of the proposed quarry sites exist in Madolenihmw, meaning that the stones must have been transported to their current location. It has been suggested that they might have been floated via raft from the quarry, and a short dive between the island and the quarries shows a trail of dropped stones. However, no one has successfully demonstrated or explained the process. Some modern Pohnpeians believe the stones were flown to the island by use of black magic.

In 1985 the ruins of Nan Madol were declared a National Historical Landmark. Currently, a greater effort is being made to preserve them.
