Black Farm, also known as the Isaac Collins Farm, is a historic farm in Hopkinton, Rhode Island bounded by Woodville Alton Road (Rhode Island Route 112) and Wood Road. The 264-acre (107ha) plot was developed by John Collins beginning in 1710 and saw agricultural use for over 200 years. The main house dates to the late 18th century, and is a 1-1/2 story gambrel-roofed post-and-beam structure. Outbuildings include 19th century barns, a corn crib, and a guest cottage added in the 1930s. Set some distance off from this complex is the foundational remains of what was probably an ice house; it consists of granite blocks and is eight feet high.[2]
The state of Rhode Island purchased the farm in 1991. A lot containing the farmstead complex was sold into private hands with a preservation easement, and the rest of the farm property is now conservation land.[2] The farm was added to the National Register of Historic Places in 1995.[1]
