Hale Koa means House of Warriors. The military structure was built in 1871 to house the Royal Guard for Kamehameha V, then ruler of the Kingdom of Hawaii. It remained the barracks for the Household Troops until the monarchy was overthrown in 1893 and the Hawaiian army was subsequently disbanded. In 1965, Hale Koa was moved and now serves as the gift shop and ticket booth for the ‘Iolani Palace.
