The 12,000 square feet, three story building was built around 1885 as a carriage factory. It was purchased in the 1890s by C. Arthur Bunn for use as feed mill, and was used as a feed mill as late as the 1980s. The Richmondville Historical Society purchased the Mill on High Street in 2002, and has reopened it as it's home and as a historical museum. It is open to the public from June through September from 9am to 1pm.
