  • What does the Twin Lights Historical Society do?
    The Society is an officially recognized friends group that has a long and unique relationship with the Twin Lights that dates back to the 1950s. The Society follows industry best practices in building, maintaining and interpreting a collection of 3,000-plus artifacts and creates museum exhibits that are always free to the public. The Society employs a part-time curator and runs internship programs for budding historians and museum anthropologists, and also oversees operation of a museum store—the profits from which support its collection and displays. The Society partners with the state on multiple projects geared toward the appreciation and enjoyment of the lighthouse by the public. The Society’s efforts are funded by low-cost memberships, on-site donations, grants and private and corporate giving.

  • Why are there two towers?
    The first Navesink Light Station was built in 1828 and consisted of two identical towers. Those “Twin Lights" gave the station a definite and decided character that helped distinguish it from the nearby Sandy Hook lighthouse and the Sandy Hook Lightship stationed offshore. When the present station was commissioned on May 1, 1862, the south tower contained a first order Fresnel lens that gave ships a warning of their approach to land. The north tower was lit by a lens of the second order, an indication to vessels they were coming up on a headland along the seacoast and the approach to a bay.
  • Why are the towers different shapes?
    We really do not know. What we do know is that several men who sat on the lighthouse board were also regents at the Smithsonian during the construction of the castle building perhaps they influenced the design at Highlands. Another explanation could be that the south tower had to be much sturdier in order to support the giant 9 foot Fresnel lens sitting atop a pot of mercury high up in the tower.
  • How tall are the towers and how many steps to the top?
    The focal plane (center) of the north tower is 246 feet above sea level. The towers have 64 steps to the observation deck in the north tower and 65 in the south tower.
