Manville has been a manufacturing center since 1711 when Israel Wilkinson opened the Unity Furnace to produce iron. Later, it was briefly home to the largest cotton mill under one roof in America, and Manville village spanned both sides of the Blackstone River to house the 2,000 mill workers who toiled here.
Parking: The tour begins at the Manville Landing, at the foot of Manville Hill Road, Cumberland, RI, adjacent to the Blackstone River.
