Boal Mansion is a historic home located at Boalsburg, Harris Township, Centre County, Pennsylvania. The original pioneer cabin was built in 1809 and was a simple 1+1⁄2-story stone house. It was incorporated as the kitchen and kitchen hall when the house was expanded. The expansion is a two-story stone house in the Georgian style which measures 30 by 50 feet (9.1 by 15.2 m) and has a side hall plan. The house was expanded again between 1898 and 1905 by Theodore Davis Boal and introduced some Beaux-Arts style design. The main façade was expanded from three to five bays.
