U.S. Army Museum of Hawaii
Located within Fort DeRussy Military Reservation, the biggest artifact of this museum is the building itself. The museum is housed in Battery Randolph a massive reinforced concrete emplacement with roofs as much as 12 feet thick. The battery was built around 1911 for two 14 inch guns that could fire projectiles as far as 14 miles. It was part of a coastal defense system that was to protect Honolulu Harbor from invasion. This museum covers the island’s military history – from its days as a U.S. possession during the 19th century.
