Pitstone Post Mill dates back to 1627 and as such is the oldest surviving windmill in the British Isles. The mill worked continuously until 1902, when after suffering damage in a storm it fell into a state of disrepair. This can be seen in the image above. It was, however, restored to near working order by a group of volunteers between 1963 and 1970; and is now owned by the National Trust. It is open to the public on Sunday afternoons throughout the summer months.
Pitstone is a village about seven miles from the town of Aylesbury in the county of Buckinghamshire in the south east of England.
