Located on Garden Key, this is a part of the coastal defense system begun after the War of 1812. Named after President Thomas Jefferson, construction began in 1846. this site remains America’s largest 19th century coastal fort. Fort Jefferson saw duty during and after the Civil War as a prison for deserters and other criminals, the most notable of which were men implicated in the assassination of President Abraham Lincoln.

Obsolete as a coastal fortification because of rifled cannon, this served as an observation post during World War II. President Franklin Roosevelt declared this site a national monument in 1935 and, in 1992, the fort became part of Fort Jefferson/Dry Tortugas National Park.
