It is located northeast of Angaur and southwest of Koror. Peleliu has a total area of 13 km2 (5 mi2) As of 2004, its population was about 700, making it the third most populous state of Palau. Most of the island's population lives in the village of Kloulklubed on the northern coast. This is the capital of Peleliu. The island was the site of the Battle of Peleliu in World War II. Peleliu is a memorial site for both WWII US and Japanese troops. Many soldiers died on the beaches and in the caves of Peleliu. Many of the military installations of the era, such as the airstrip, are still intact, and shipwrecks from the battle remain visible underwater just off the coast. A US Navy ship USS Peleliu (LHA-5) is named for the battle.
