Built in 1876, Fort Jefferson Lighthouse (also known as Garden Key Ligjt) helped warn sea traffic away from the dangerous shoals and reefs that surrounded the Florida Keys until it was deactivated in 1912 but currently acts as a harbor light, guiding vessels safely into the anchorage outside Fort Jefferson. Today the hexagonal lighthouse is part of Dry Tortygas National Park.
