SIGN UP: Last month, Octagon House Restoration Inc. Chairman Walter Baum erected the Hyde County house’s new sign, which features a QR code to scan on a mobile device for more information. The circa-1857 Octagon House is only one of two antebellum-era octagonal houses left standing in North Carolina. In late 2017, roofing repairs were completed on the home, as part of the latest phase of renovations. Hyde’s Octagon House is located off of U.S. Highway 264 in Engelhard.
