The Putnam County Historical Museum is a local history museum in Palatka, Florida. It is best noted for its relationship with the Seminole War.

The Putnam County Historical Museum is quite a rare and unusual place to visit, especially since it is one of the only two structures left in the state that has once been a part of the 250 Seminole War forts. The structure that houses the museum is actually the officer?s quarters used in the Fort Shannon in Palatka. Today, it is continuously being used and preserved by the Putnam Historical Society as its home.

The Putman County Historical Museum features a wide range of displays, most of which tell of the local history of the city and the Palatka County.
