The fort covers 10 acres of gun emplacements and tunnels created by the British to fend off the Japanese. Unfortunately, the Japanese arrived by land (through Malaysia) instead of by sea, so the huge guns were pointed in the wrong direction. Fort Siloso is now home to the nation's largest collection of World War II memorabilia. The displays have been successfully revamped with lots of interactive high-tech audiovisual and animatronic effects. Photographs document the war in the Pacific, and dioramas depict the life of POWs during the Japanese occupation. Free guided tours are available at 12:40 pm and 3:40 pm. on Fri.–Sun. and on public holidays.
