The Fort Canning Bunker, also known as the Battlebox, is a World War II-era command bunker located beneath Fort Canning Hill in Singapore. Constructed in the late 1930s as part of British defensive preparations, this underground facility served as the Headquarters Malaya Command Operations Bunker during the Malayan Campaign and the Battle of Singapore. The bunker was designed as an emergency, bomb-proof command center to coordinate military operations in the region.
Today, the Battlebox operates as a museum and tourist attraction, offering visitors insight into Singapore's wartime history and the events leading up to the fall of Singapore in 1942.
