Light Hearted ep 208 – Rob Dixon and Larry Herlth, Alligator Reef, Florida

The Florida reef lights date back to 1852 when Carysfort Reef Lighthouse was completed under the direction of Lt. George Meade of the Army Corps of Engineers. Sombrero Key Lighthouse was built a few years later, and then Alligator Reef was built as the third of the reef lights in 1873. Alligator Reef Lighthouse is about four nautical miles offshore from the village of Islamorada. The reef is named for the U.S. Navy schooner Alligator, which was launched at Boston in 1820.

The lighthouse was established on the northeast end of the reef in 1873, with a light 136 feet above the water. The iron skeletal tower stands on pilings that are driven 10 feet into the coral. The cost of construction was $185,000, making it a very expensive project at the time. The light was automated and de-staffed in 1963. In 2021, under the National Historic Lighthouse Preservation Act, the lighthouse was deeded to Friends of the Pool, Inc., a local nonprofit organization that has held an annual eight-mile round-trip swimming race to the lighthouse.
