Fort Kamehameha in Honolulu was built in 1916 as a U.S. Army Coastal Artillery Post to defend Pearl Harbor from 1907 onward. The fort's strategic battery system protected the developing naval base and represented a key element of Hawaii's coastal defense infrastructure. The historic district preserves 33 bungalow-style homes built in 1916 with Arts and Crafts design, earning a spot on the National Register of Historic Places in 1984. Following World War II, when coastal artillery became obsolete, much of the fort became integrated into Hickam Air Force Base in 1992.
