Corregidor

Corregidor Island, locally called Isla ng Corregidor, is an island located at the entrance of Manila Bay in southwestern part of Luzon Island in the Philippines. Due to this location, Corregidor was fortified with several coastal artillery and ammunition magazines to defend the entrance of Manila Bay and the city of Manila from attacks by enemy warships in the event of war. Located inland, Manila has been the largest city and the most important seaport in the Philippines for centuries, from the colonial rule of Spain, Japan and the United States, to the establishment of the Republic of the Philippines in 1946.
