text: Sanibel Island, Fl. -- The Sanibel Island Light or Point Ybel Light was one of the first lighthouses on Florida's Gulf coast north of Key West and the Dry Tortugas. The light, 98-foot above sea level, on an iron skeleton tower was first lit on August 20, 1884 and has a central spiral staircase beginning about 10 feet above the ground. The grounds are open to the public, but not the lighthouse itself. Photo by Peter W. Cross
