The Buttonwoods Museum is comprised of several structures including three main buildings: the 1814 Duncan Mansion, the 1859 Daniel Hunkins Shoe Shop, and the 1710-1810, and the John Ward House. The museum is operated by the Haverhill Historical Society, which is headquartered in the Duncan House. The buildings are listed collectively on the National Register of Historic Places as the Haverhill Historical Society Historic District. The society acquired the Duncan property in 1903. In addition to the historic buildings and their contents, the museum also features Native American artifacts and a large collection of shoes and shoe making tools (Haverhill has been a leading location for shoe manufacturing).
