Visitors often encounter Ulithi Atoll through the idea of “Cross part of the lagoon in a traditional sailing canoe”, but the destination is more than that single scene.

Lives and livelihoods
People, work and memory
Ulithi's island communities belong to the wider Yapese cultural sphere, with customary chiefs, navigational knowledge and inter-island exchange organising life across a very large lagoon. Spanish, German and then Japanese colonial administrations imposed changing external systems without erasing local tenure and language.
Japan developed a communications and seaplane presence before the Second World War. In 1944 the United States seized the atoll and converted its lagoon into the principal forward anchorage for the western Pacific fleet. Hundreds of ships assembled inside the reef, supplied by floating docks and service vessels before operations toward the Philippines, Iwo Jima and Okinawa.

Modern history
A landscape reorganised
The wartime base briefly turned a small atoll into one of the world's largest naval concentrations, then disappeared almost as quickly. Wrecks, military debris and altered shorelines remain, but the enduring geography is still the customary network of inhabited islets, canoe routes and reef passages.
