Diamond Head Lighthouse
Honolulu, South Shore

Located on a steep cliff on the flank of Diamond Head crater, the lighthouse is one of Hawaii's oldest ocean navigation aids. The tower is 55 feet high and the tower's light can be seen almost 18 miles away and is one of the best-known beacon lights in the Pacific. Entry into the building has been restricted indefinitely. The Diamond Head Lighthouse is on the National Register of Historic Places in 1980.
