You’ll recognise Turville even if you’ve never been: the flint church and brick cottages played the village in The Vicar of Dibley, and the smock mill on the hill above was Caractacus Potts’s home in Chitty Chitty Bang Bang. It’s a genuine hamlet in a steep Chilterns bottom, with the Bull and Butcher on the green. The windmill is private, seen from the footpaths only.
