Navesink Twin Lights
lighthouse in New Jersey, United States
The Navesink Twin Lights is a non-operational lighthouse and museum located in Highlands, Monmouth County, New Jersey, United States, overlooking Sandy Hook Bay, the entrance to New York Harbor, and the Atlantic Ocean. The Twin Lights, as the name implies, are a pair of beacons located 246 feet (75 m) above sea level on the headlands of the Navesink Highlands.
In 1962, the State of New Jersey acquired Twin Lights. The museum offers tours of the lighthouse, and a climb of the North Tower. 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.
The Twin Lights State Historic Site is part of the New Jersey Coastal Heritage Trail Route.
History
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.
This was the first American lighthouse to test a Fresnel lens and was also the site of a demonstration by Marconi of the wireless telegraph in 1899.
