Visiting Dry Tortugas National Park
Ponce de Leon sailed through the waters off the southwestern coast of Florida in 1513 and, noting the abundance of sea turtles, named them Las Tortugas ("the turtles"). They later became known as the Dry Tortugas, owing to the lack of fresh water.
The centerpiece of the park is Fort Jefferson, the largest brick and masonry structure in the Western Hemisphere and the biggest fort still standing from the 19th century. From the standpoint of natural history, the park is important to the region in that it protects seven coral islands -- the Dry Tortugas, the most pristine coral reef in the continental United States.
