Fire Island is one of a chain of barrier islands running along the south shore of Long Island, New York. The first lighthouse on Fire Island was a 74-foot-high stone tower built in 1826. It was considered too short, so the much taller brick lighthouse that still stands was built in 1858. The new tower was fitted with a powerful first-order Fresnel lens. The light was decommissioned as an aid to navigation on December 31, 1973. The Fire Island Lighthouse Preservation Society was formed in 1982. Four years later, the lighthouse returned to duty as an aid to navigation.
Today, visitors can tour the museum in the keeper’s house, with two floors of exhibits. Visitors can also view the old first-order Fresnel lens, which is on display in a separate building. The guest in this episode, Jonathon Gaare, became the executive director of the Fire Island Lighthouse Preservation Society earlier this year.
