Chesterton Windmill on a real cold day.

Chesterton Windmill is just off the Fosse Way (an old Roman Road also known as the B4455), about five miles to the south of Leamington Spa, near the village of Harbury in Warwickshire. OS Grid reference SP348594
This unique windmill stands on six stone pillars, supporting two raised floors. It was built in 1632, and worked until 1910 when its machinery broke down. It not clear if it was originally intended as a functional windmill, or as a folly - an observatory has been suggested, which in many ways makes more sense.
