Which windmill was used in the film "Chitty Chitty Bang Bang"?

Cobstone Mill was built around 1816 on Turville Hill in Buckinghamshire, England, and overlooks the village of Turville. It is a smock mill that replaced the original mill that had stood there since the 16th century. The machinery was previously used in another mill in the village of Lacey Green.

It was a working mill grinding cereal until 1873. Later, squatters living in the mill caused a fire which damaged the centre post. After this time the mill went further into deterioration. In 1967, for the filming of "Chitty Chitty Bang Bang", the mill was cosmetically restored. 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.

"Chitty Chitty Bang Bang" is a 1968 musical-fantasy film directed by Ken Hughes with a screenplay co-written by Roald Dahl and Hughes, loosely based on Ian Fleming's novel "Chitty-Chitty-Bang-Bang: The Magical Car" (1964). The film stars Dick Van Dyke, Sally Ann Howes, Adrian Hall, Heather Ripley, Lionel Jeffries, Benny Hill, James Robertson Justice, Robert Helpmann, Barbara Windsor and Gert Fröbe.
