Original pen & ink rendering. Located on Loggerhead Key, the westernmost key in Dry Tortugas National Park. The lighthouse was first illuminated on July 1, 1858. Loggerhead Key, as the name implies, is a nesting place for the Loggerhead Turtle, and they return to the island each year to lay their eggs. In 1992, Loggerhead Key was included in Dry Tortugas National Park, and the grounds are open to the public, but the tower is not.
