What does the Bailey-Matthews National Shell Museum cover?

The museum looks at shells as part of mollusk life, ecosystems and human culture. Incorporated as a nonprofit in October 1986, it opened to the public in 1995. Its name recognizes two Sanibel families: the Bailey brothers donated the land, and Harriet (“Hallie”) Matthews hosted the first Shell Festival in 1937.
The Great Hall of Shells draws on a collection of more than 600,000 shells. Its exhibits cover mollusk habitats and the roles shells have played in art, currency, architecture, music, tools, spirituality, fashion and medicine. The scope makes the museum relevant beyond shell collecting, with connections to natural history and everyday life.
Environmental topics are part of the story, too. Exhibits address habitat loss, climate change and water quality, alongside conservation work such as oyster habitat restoration and Queen Conch recovery. For another perspective on island history, the Sanibel Historical Museum and Village focuses on local history and heritage.
What can you see and do at the museum?

The Living Gallery features more than 60 species of marine life. The regional tourism organization describes activities that can add a more hands-on or guided element to a visit, including keeper chats with aquarists, touch pools and touch-pool talks.
