The Old Mill,

50 Prospect St, Nantucket, MA 02554, United States

The Old Mill, located at 50 Prospect Street in Nantucket, Massachusetts, is a historic institution that is free to all visitors. Open on select days from 11am to 4pm, the Old Mill is believed to be the oldest operating windmill in the United States. Built in 1746, the mill has a rich history of restoration and operation, grinding corn just as it did over two centuries ago. Visitors can witness the mill in action when wind and weather conditions permit, with millers explaining the process of grinding corn into cornmeal. The Old Mill is not wheelchair-accessible due to its authentic 18th-century architecture, with tall steps and narrow doorways that may present difficulties for those with physical disabilities. Service animals are welcome, but pets should be left at home. The Nantucket Historical Association, which owns and operates the Old Mill, aims to preserve and share the diverse stories of Nantucket through its collections, properties, programs, and research.
