The Florida Keys possess a staggering wealth of lighthouses—nine in all, from the remote iron light at Fowey Rocks to classic brick structures at Key West and Loggerhead Key. In the 1820s, the US government began constructing lighthouses to aid mariners navigating the dangerous Florida Reef. While some of the original lights were subsequently destroyed in dramatic circumstances, most that followed, including Carysfort Reef, Alligator Reef, Sombrero Key, Sand Key, and American Shoal, survived intense tropical weather and even major hurricanes. Among the lighthouse keepers were remarkable women who succeeded in a profession usually reserved for men.
