The northern half of the island is scattered with the rusted remains of the 1944 American landing — landing-craft hulks on the beach, twisted artillery pieces in the trees, concrete bunkers and Japanese gun emplacements pulled into the jungle by sixty years of vines. Nothing is fenced off and very little is interpreted; you walk up to it and decide for yourself what you are looking at.
The most visible features are the two coral-strip airfields built during the battle, both still discernible from the air although the jungle has reclaimed the edges. Phosphate-mine workings from the Japanese period also dot the north of the island; the caves and tunnels here were where the last defenders held out. Locals will point them out if asked.
