Cobstone Mill was built around 1816 on Turville Hill in Buckinghamshire, England, and overlooks the village of Turville.The machinery was previously used in another mill in the village of Lacey Green.Later, squatters living in the mill caused a fire which damaged the centre post.The cap was remoulded, and a new fantail and light wooden sails added.The mill and cottage were purchased in 1971 by Hayley Mills and her first husband Roy Boulting, and extensive conversions and remodelling of the interiors were completed as well as interior and exterior restoration and conversion of the mill.
