Corregidor Island is a tadpole shape, rocky island, strategically located at the entrance of Manila Bay which falls under the jurisdiction of Cavite.
After the Spanish-American War, it became a military station. Defense guns, anti-aircraft batteries, mortars, tunnels, and barracks were added to the fortification. During world war 2, it was the last fortress captured by the Japanese imperial army before the Americans and Filipino forces surrendered under the command of Lt. Gen. Jonathan Wainwright.
