Gayle Mill, dating from about 1784, is thought to be the oldest structurally unaltered cotton mill in existence. It is located in the Wensleydale hamlet of Gayle, England, 1 mile (2 km) south of the market town of Hawes. It lies within the Yorkshire Dales National Park. The mill is owned by Cultura Trust (formerly known as the North of England Civic Trust ; it was operated by a local volunteer group which paid a modest rent to the owner until March 2018 when the property was closed to enable additional repairs to be undertaken to make it safe for visitors.
