Built circa 1850, this historic structure is a large, two-story, five-bay, rectangular, limestone building, which measures forty-two feet, four inches across and thirty-four feet, two inches, deep. Designed in the Georgian style, it has a low pitch, gable roof and a center hall plan interior. A rear kitchen ell was added in 1913. It was home to two prominent residents: Hugh N. McAllister, one of the founders of the Pennsylvania State University, and Gov. James A. Beaver.[2]
