Address: Corregidor Island, Philippines

The Malinta Tunnel was excavated through Malinta Hill by the United States Army Corps of Engineers in the early 1930s as bomb-proof storage and personnel quarters, and was later outfitted as a 1,000-bed hospital. The main east-west gallery is 831 feet (253 m) long, about 24 feet (7.3 m) wide and 18 feet (5.5 m) high, with 13 lateral tunnels on the north side and 11 on the south.

The tunnel takes its name from Malinta Hill; Malinta is Tagalog for “many leeches.” Construction began in 1932 and much of the system was completed by 1934 using labor provided by the Philippine Commonwealth (including 1,000 convicts from Bilibid Prison) and adapted equipment. During World War II the tunnel served as General Douglas MacArthur’s headquarters and as the seat of the Commonwealth government while Corregidor held out.

In 1945 sections of the tunnel collapsed after explosions during the island’s recapture; several laterals remain unexcavated. Today the tunnel houses an audio-visual presentation recounting events from the war and a small memorial plaque, and visiting it gives a vivid sense of the island’s wartime role and the confined, dim environment used for hospital wards and command rooms.

  • Main Gallery: Walk the long central shaft that served as the tunnel’s principal artery and imagine its wartime uses as storage, shelter and hospital wards.
  • Lateral Tunnels: Explore the branching north and south laterals that once contained wards, offices and support rooms; some laterals are blocked or collapsed from wartime damage.
  • Audio-Visual Presentation: The tunnel hosts a timed audio-visual program that presents Corregidor’s World War II history, evacuation of officials, and the island’s military actions.
  • Presidential and Command Area: See the area associated with General MacArthur and the Commonwealth government, and learn of the oaths taken by President Quezon and Vice-President Osmeña on the island.
  • Memorial Plaques: View plaques and markers inside the tunnel that commemorate events, units and people connected with Corregidor’s wartime past.
