The Dry Tortugas

Fort Jefferson

Fort Jefferson is located on Garden Key. This all-masonry fort is the largest in the United States. It was built between 1846 and The long stretch of time to build the fort was delayed not only by supply problems but also the Civil War. The fort was never completed but the existing structure has some beautiful brickwork features including some 2,000 arches. Restoration is constantly underway to preserve Fort Jefferson.

The islands were discovered by Ponce de Leon in 1513 and the multitude of sea turtles that populated the area gave the islands their name. Tortugas means turtles in Spanish. The “Dry” part comes from the lack of freshwater anywhere.
