The Aloha Tower stands 184 feet tall and is a ten story concrete structure that was constructed in 1926. The tenth floor has a projecting observation balcony, and the structure features a convex curved hip roof. Atop the roof is a flag mast for maritime signal flags. The Aloha Tower continues to function as the Harbor Master’s traffic control center of Honolulu Harbor and serves as a welcoming landmark. The tower features a seven ton clock which is weight driven. The Aloha Tower was the tallest structure in the Hawaiian islands and its clock was one of the largest in the United States when constructed. The Aloha Tower is significant for its associations with sea travel to Oahu, and for the use of the tower as a center for the planning of military convoy operations during World War II.
