Winn Farm is a historic farmhouse at 57 Summer Street in Arlington, Massachusetts, USA. The 2+1⁄2-story wood-frame house is estimated to have been built c. 1820, and is the only surviving farmhouse in northwestern Arlington from that period. It is a typical Federal style house, five bays wide, with a center entrance, standing in a part of the town that was not developed more fully until the 20th century. Albert Winn, its likely builder, was active in local civic affairs, serving in town offices and as a state representative.[2]
