Colerain Forges Mansion
SeasonalAn ironmaster's mansion begun around 1800 on Spruce Creek Road in Franklin Township, with guided tours on Sundays, May to October.
Colerain Forges Mansion is an ironmaster's house on Spruce Creek Road in Franklin Township. The site says it was started around 1800, with additions by ironmaster David Stewart and his family from the 1830s through the 1860s. The National Register of Historic Places listed it in 1990, and its grounds include 10 acres of woods and formal gardens.
Historical tours run on the first and second Sundays of each month, May to October, at 11 a.m., 1 p.m. and 3 p.m., and last about an hour. Executive director Dave Petit guides them. The site says Colerain produced 29,616 tons of wrought iron blooms from 1823 to 1860. Walk-ins are accepted, though tickets bought in advance are preferred.
Tours cost $10 for adults and $5 for children ages 6 to 16. Tours outside the regular dates can be booked by appointment for $15 per person. The Colerain Center for Education, Preservation, and the Arts received the mansion and its grounds as a gift in 2019.
