The Venice of the Pacific
The Federated States of Micronesia (FSM) — four states (Yap, Chuuk, Pohnpei, Kosrae) across ~607 islands in the Central Pacific — is home to one of the world’s most mysterious archaeological sites: Nan Madol. Built between 1100 and 1628 AD on 92 artificial islets in a lagoon on Pohnpei using enormous basalt megaliths (many weighing 50+ tonnes), Nan Madol served as the ceremonial capital of the Saudeleur dynasty. How the basalt was transported and stacked remains archaeological mystery. The site is a UNESCO World Heritage Site.
Chuuk Lagoon is the world’s greatest wreck-diving site — during WWII’s Operation Hailstone (February 1944), the US destroyed the Japanese Pacific Fleet’s main base here, sinking approximately 60 ships and 275 aircraft. These wrecks are largely intact and accessible to recreational divers.
Yap is famous for its stone money (rai) — enormous disc-shaped limestone stones up to 4 m in diameter, quarried on Palau centuries ago and transported by canoe. Still used ceremonially, each stone has a known ownership history and value (based on size, difficulty of transport, and history). This is one of the world’s oldest continuous currency systems and frequently cited in economics papers.
FSM has a Compact of Free Association with the US similar to the Marshall Islands — free Micronesian movement to the US and US defence responsibility.
