In 1962, the State of New Jersey acquired Twin Lights. At the current museum facility, tours of the lighthouse, a climb of the North Tower and its expansive ocean view, and a view of the lighthouse equipment, await visitors. Twin Lights is listed on the State and National Register of Historic Places, and was designated a National Historic Landmark in 2006 for its architecture and its role in the development of lighthouse technologies.[5]
A lighthouse existed on the site since 1828, when it became an important guide and landmark for ships navigating the treacherous entrances to New York Harbor.
The current lighthouse was constructed in 1862. The non-identical towers by day and the two beacons by night—one flashing and one fixed—allowed ready identification by mariners of the identity of the facility, thus allowing a rough determination of their location approaching the harbor.
The north tower light was discontinued in 1898; at the same time the south tower was electrified, one of the first lighthouses in the United States to do so. It was automated in 1949, but was discontinued in 1952 as the importance of the light diminished.
In 1962, the site was turned over to the state of New Jersey, by the Borough of Highlands.[8] The sixth order lens was previously acquired and installed in the north tower by the Shrewsbury Power Squadron and presented to the town which reactivated the north tower as a private aid to navigation. This light remains active.
