Kranji Cemetery commemorates the Allied men and women who fought and died in World War II. Prisoners of war in a camp nearby began a burial ground here, and after the war it was enlarged to provide space for all the casualties. The Kranji War Cemetery is the site of 4,000 graves of servicemen, while the Singapore State Cemetery memorializes the names of over 20,000 who died and have no known graves. Stones are laid geometrically on a slope with a view of the Strait of Johor. The memorial itself is designed to represent the three arms of the services.
