US-Lighthouses had the opportunity to visit New Jersey in April of 2010. We were able to cover most of the state and got to climb quite a few of the towers. The state houses some interesting lighthouses and history. For one, there is the Twin Lights at Navesink. The lighthouse looks very much like a fortress and was the first lighthouse in the US to use a Frensel lens. It is also the first seacoast light to be powered by electricity.
Another interesting lighthouse, Sandy Hook, is the oldest working lighthouse in the US and it was paid for by residents of New York, yet it is actually in New Jersey. Below are the links:
