War in the Pacific National Historical Park

The War in the Pacific National Historical Park is a multi-unit protected area in the United States territory of Guam, which was established in 1978 in honor of those who participated in the Pacific Theater of World War II. Uniquely among the National Park System, it honors the bravery and sacrifices of all those who participated in the Pacific Theater.

During World War II, Guam was captured by the Japanese forces in 1941, occupied for four years, and liberated by the Americans in 1944. The park includes former battlefields, gun emplacements, trenches, caves, and historic structures.
