The Florida Keys Lighthouse is a historic structure located in the Florida Keys, a chain of islands off the southern coast of Florida. These lighthouses were built to guide ships safely through the often treacherous waters of the Atlantic Ocean and the Gulf of Mexico. The most famous among them is the Key West Lighthouse, which was first lit in 1825 and has become a popular tourist attraction. Many of the lighthouses in the Florida Keys are part of the Florida Keys National Marine Sanctuary, which protects the area's unique marine environment. Visitors can explore these lighthouses, learn about their history, and enjoy stunning views of the surrounding ocean and islands.
