Lighthouses appeal to the romantic in all of us, and Florida has its share of these iconic landmarks lining the coasts. This spider- legged structure, which dates from 1873, sits atop a reef in the Florida Keys named for the USS Alligator, a Naval Schooner that foundered on the coral shallows. The light sits four miles east of the village of Islamorada. It is closed to the public and can only be reached by boat. A local Keys artist now stages the Annual Swim for Alligator Lighthouse event to raise awareness for the preservation of lighthouses. Photo: Rob O’Neal/Key West Seaplanes
