The Colerain Forges Mansion is a historic home located at Franklin Township in Huntingdon County, Pennsylvania.
It was built in four stages between the late-18th century and mid- to late-19th century. It appears as a two-story, five-bay, T-shaped dwelling with a one-story, full-length porch in the Federal style. The oldest section is the two-story, plastered midsection. The frame portion to the east dates to the 1830s, and the brick section to the west to the 1840s. The rear section dates to the 1860s-1870s, and is a two-story board-and-batten structure. Also on the property is a -story, gable roofed stone outbuilding and a small board-and-batten shed. The house was built as the ironmaster's mansion at Colerain Forge.[1]
It was listed on the National Register of Historic Places in 1990. The house and property are currently managed by a nonprofit, the Colerain Center for Education, Preservation, and the Arts.
