Map of The Philippines- There are more than seven thousand islands in the Philippine Archipelago and these are divided into three major groups of islands: Luzon, Visayas, and Mindanao. Luzon, as shown in this map, is in the northern part of the country, the Visayan islands in the central part, and the different islands that form the Mindanao group are in the southern part. Corregidor, a part of the Luzon group of islands, is located at the mouth of Manila Bay and lies between the provinces of Bataan and Cavite.
Map of Corregidor- The portrayed map of Corregidor which was prepared in December 1941 identifies the different road and railroad networks, gun emplacements, the airfield, tunnels, boat landing docks, buildings and structures that were constructed in the Island of Corregidor before the outbreak of World War II. Except for some newly constructed buildings and structures, landmarks, and the concreting of most of the main roads, nothing very significant has changed in the way the island looked just after the end of World War II.
Map of The Island Group- This is a larger scale map portraying Corregidor and the four nearby islands of Caballo, La Monja, El Fraile, and Carabao. Except for the island of La Monja, all these small islands were fortified into impregnable fortresses for the defense of the Philippine capital against invaders attempting entry into Manila Bay by way of the South China Sea.
