Johore Battery

The British built the Johore Battery in 1939 at the start of World War II, as a gun emplacement site consisting of a labyrinth of tunnels. These tunnels were built to store ammunition to support three 15' inch guns, also known as Monster Guns because of their colossal size. They were the biggest and heaviest coastal artilleries and were able to pierce the armour of battleships. Before Singapore fell into the hands of the Japanese, it is said that orders were sent out to destroy the guns. Tunnels were sealed up after the war.
