Mercer Museum

The Mercer Museum is a museum located in Doylestown, Pennsylvania, United States. The Bucks County Historical Society operates the Mercer Museum, as well as the Research Library, and Fonthill Castle, former home of the museum's founder, archeologist Henry Chapman Mercer. The museum was individually listed on the National Register of Historic Places in 1972, and was later included in a National Historic Landmark District along with the Moravian Pottery and Tile Works and Fonthill. These three structures are the only poured-in-place concrete structures built by Mercer.
