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 North 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 48 kilometres (30 mi) 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.
