Seawall and Moat Wall Details

A seawall was built around Fort Jefferson to protect it from assault and rough ocean waters. The space between the fort and the wall is referred to as a moat. Swimming in the moat isn't allowed, however swimming outside the Moat Wall is. There, snorkelers will discover various marine life from reef squid to nurse sharks. Snorkeling the Moat Wall at night is an exciting experience as nocturnal creatures such as octopus and lobster can be spotted. Visitors enjoy walking atop the six-foot-wide seawall, which circles the brick fort.
