Timothy Stone built this cider mill in 1820, and it operated until 1910. It is architecturally significant as a rare, if not unique, purpose-built cider mill with its equipment intact, including two cider presses and a horse-driven "nut mill" used to chop apples before pressing, and as a well-preserved example of timber framing used to create the large open space needed for cider making. The building and surrounding land have remained in the ownership of members of the Stone family since their purchase in 1715, and the mill and surrounding land will be preserved under a historic easement granted to Preservation CT in 2014, with no further development to take place.
