ʻIolani Barracks, or hale koa[2] (house [of] warriors)[3] in Hawaiian, was built in 1870, designed by the architect Theodore Heuck, under the direction of King Lot Kapuaiwa.

Located directly adjacent to ʻIolani Palace in downtown Honolulu, it housed about 80 members of the monarch's Royal Guard until the overthrow of the Monarchy in 1893.

It was constructed with 4,000 coral block walls from the same limestone source used to build Kawaiahaʻo Church and the Cathedral of Our Lady of Peace and has a slate roof.

After the overthrow of the Hawaiian monarchy in 1893, the Royal Guard were paid their month's salary and disbanded.
