This view of the windmill featured in the film Chitty Chitty Bang Bang is spoiled by the power lines that run behind the cottages in Turville.
The Cobstone Windmill, in addition to serving as Caractacus Potts' workshop, was featured in other films, including Goodnight Mr. Tom, Bride and Prejudice, Dead of Night, and scenes of "Little Britain". It once belonged to Hayley Mills.
It's actually located in Ibstone, near Turville, which is a great area for hikes. And for cows—check back tomorrow.
