Was the plan of this atypical Federal town house once common in Lewistown? Since few early-nineteenth-century houses escaped the modernization of the town center, the McCoy House documents a rare regional style. The two-and-one-half-story brick and frame residence is a four-bay side-hall plan instead of the usual three bays. The recessed arched entrance is raised above street level and accessed by a short flight of steps to accommodate the basement. This has its own entrance and two windows on the front of the house and is enclosed by an iron railing. The first- and second-story six-over-six windows with paneled shutters are traditional, but the two gabled dormers on the roof are not in the standard alignment with the windows below. Above the paneled door is a recessed fanlight that is echoed on the double-chimney gable end facing Market Street, which also has two small square basement windows. The house carries the name of Major General Frank Ross McCoy, who was born here in 1874 and had a distinguished career during World War I. The Mifflin County Historical Society maintains the house as a museum with Victorian furnishings and memorabilia.
