In 1513, Don Juan Ponce de Leon discovered the islands of the Dry Tortugas 70 miles west of Florida. By the time #Florida was acquired by the United States in 1821, military strategists of the young nation already had plans for this vital anchorage. Construction on Fort Jefferson began in 1846, but was hindered by heat, hurricanes, disease and distance. Today, #DryTortugas National Park preserves the fort, as well as the marine ecosystems and island beauty that mesmerize everyone who visits.
