Built in 1958 by the United States Coast Guard, the Oak Island Light Station is unique in that it was designed using the most advanced construction techniques of the 20th century and was one of the last light stations to be built in the United States. With its structurally reinforced eight-inch-thick concrete walls, Oak Island does not have the tapered look of most lighthouse towers.
The plumb vertical walls rise 155 feet with a focal plane of 169 feet above sea level. When built, colors were added to the concrete in order to save on future maintenance costs so that it will never have to be painted. The tri-colored day mark consists of black, white, and grey.
Built on Caswell Island, the lighthouse was placed in its strategic site to aid shipping into and out of the Cape Fear River from the Atlantic Ocean and to warn of the dangers of Frying Pan Shoals. With its four twenty-four-inch parabolic mirrors and four 1000-watt bulbs, the Oak Island beacon was once considered one of the most powerful in the United States with a range of sixteen miles.
