Nan Madol is a ruined city that lies off the eastern shore of the island of Pohnpei that was the capital of the Saudeleur dynasty until about 1628.[note 1] It is in the present day Madolenihmw district of Pohnpei state, in the Federated States of Micronesia in the western Pacific Ocean. The city consists of a series of small artificial islands linked by a network of canals. 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.
The name Nan Madol means "spaces between" and is a reference to the canals that crisscross the ruins. The original name was Soun Nan-leng (Reef of Heaven), according to Gene Ashby in his book Pohnpei, An Island Argosy. It is often called the "Venice of the Pacific
Nan Madol was the ceremonial and political seat of the Saudeleur dynasty, which united Pohnpei's estimated 25,000 people until about 1628. Set apart between the main island of Pohnpei and Temwen Island, it was a scene of human activity as early as the first or second century AD. By the 8th or 9th century islet construction had started, but the distinctive megalithic architecture was probably not begun until perhaps the 12th or early 13th century.
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 at off Temwen Island, where they performed their rituals. In legend, these brothers levitated the huge stones with the aid of a flying dragon. When Olisihpa died of old age, Olosohpa became the first Saudeleur. Olosohpa married a local woman and sired twelve generations, producing sixteen other Saudeleur rulers of the Dipwilap ("Great") clan.[note 2] The founders of the dynasty ruled kindly, though their successors placed ever increasing demands on their subjects. Their reign ended with the invasion by Isokelekel, who also resided at Nan Madol, though his successors abandoned the site.
Purpose and features 
The elite centre was a special place of residence for the nobility and of mortuary activities presided over by priests. Its population almost certainly did not exceed 1,000, and may have been less than half that. Although many of the residents were chiefs, the majority were commoners. Nan Madol served, in part, as a way for the ruling Saudeleur chiefs to organize and control potential rivals by requiring them to live in the city rather than in their home districts, where their activities were difficult to monitor.
Madol Powe, the mortuary sector, contains 58 islets in the northeastern area of Nan Madol. Most islets were once occupied by the dwellings of priests. Some islets served special purpose: food preparation, canoe construction on Dapahu, and coconut oil preparation on Peinering. High walls surrounding tombs are located on Peinkitel, Karian, and Lemenkou, but the crowning achievement is the royal mortuary islet of Nandauwas, where walls 18–25 feet (5.5–7.6 m) high surround a central tomb enclosure within the main courtyard.
Supposedly there was an escape tunnel beginning at the center of Nan Madol and boring down through the reef to exit into the ocean. Scuba divers continue to look for this "secret" route, but so far a complete tunnel has not been discovered.
Food and water 
On Nan Madol there is no fresh water or food; water must be collected and food grown inland. During Saudeleur rule, Pohnpeians brought essential food and water by boat. The Saudeleur received food at a particular islet — first Peiniot, and later the closer Usennamw.
Around 1628, when Isokelekel overthrew the Saudeleurs and began the Nahnmwarki Era, the Nahnmwarkis lived at Nan Madol, but had to gather their own water and grow their own food. This is thought[who?] to have caused them eventually to abandon Nan Madol and move back to their own districts, although there are other explanations for the deserting of the complex, such as a sharp population decline.
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 1200 CE, while excavations show that the area may have been occupied as early as 200 BCE. 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.
In fiction 
Nan Madol has inspired a number of works of fiction about lost civilisations:
- The ruins of Nan Madol were used as the setting for a lost race story by A. Merritt, The Moon Pool (1918), in which the islands are called Nan-Tauach and the ruins are called the Nan-Matal.
- Nan Madol is the name of an album recorded by Edward Vesala in 1974.
- Nan Madol and its history have been used as the basis of the novel Deep Fathom (2001) written by James Rollins.
- It is also featured in Clive Cussler's 2009 novel Medusa.
- The novel "The Ultimate Aphrodisiac" by Robert G. Barrett is set in the fictional Micronesian Island of Lan Laroi, which was inspired by Barrett's visit to Nan Madol.
- Nan Madol was one of the sites James Churchward identified as being part of the lost continent of Mu, starting in his 1926 book The Lost Continent of Mu Motherland of Man.
- In his book Lost City of Stones (1978) writer Bill S. Ballinger theorizes the city was built by Greek sailors 300 years before the time of Christ.
- David Hatcher Childress, an author of travel guides, speculates that Nan Madol is connected to the lost continent of Lemuria.
- The 1999 book The Coming Global Superstorm by Art Bell and Whitley Strieber, which predicts that global warming might produce sudden and catastrophic climatic effects, claims that the construction of Nan Madol, with exacting tolerances and extremely heavy basalt materials, necessitated a high degree of technical competency. Since no such society exists in the modern record - or, even, in legend - this society must have been destroyed by dramatic means.
- See also the book by Erich Von Daniken "the gold of the gods", 1972.
- The Saudeleur era lasted around 500 years. Legend generally dates their downfall to the 1500s, however archaeologists date Saudeleur ruins to ca. 1628.
- Hanlon (1988) notes differing accounts of the number of Saudeleur rulers, ranging from eight to seventeen, concluding that it is impossible to know this number for certain.:234
