Mel Fisher Maritime Museum is a shipwreck archaeology and history museum in Old Town Key West, focused on maritime life around Florida and the Caribbean. It's at 200 Greene Street, and it suits visitors who want the stories behind the recovered objects as well as the treasure itself. Give the displays time: they work as a self-guided visit, and visitors who read through them report spending an hour or longer. A separate conservation-lab tour is the add-on for seeing how artifacts are treated after recovery.
