Pitstone Windmill stands in the north east corner of a large field near the parish boundary of Ivinghoe and Pitstone in Buckinghamshire. It is thought to have been first built circa 1627 as this date is carved on part of the framework. This is the earliest date to be found on any windmill in the British Isles. It should be remembered that such a structure would have had to have frequent repairs made to it, so it is quite possible the mill predates 1627.
The design of the mill is what is known as a post-mill. This means the whole superstructure of the mill rests on one main post. This post arises from ground level through brick and a foundation chamber; the post then acts as a pivot for the timber built structure above with the sails. Consequently, the upper section of the mill and sails can be turned towards the direction of the wind. The mill machinery in the upper rotating section was reached by a long flight of external steps.
In 1902 the mill was seriously damaged during a furious gale, damaging it beyond the price of economic repair. Circa 1922 the now derelict ruined mill was bought from the Ashridge Estate by a farmer whose land was close to the mill. In 1937 he donated it to the National Trust. However, it was not until 1963 that a band of volunteers began to carry out renovations at their own expense. After seven years of hard work in 1970 after an interlude of 68 years the mill once again ground corn.
Today owned by the National Trust the windmill is open to the public on Summer Sunday afternoons.

A windmill is an engine powered by the energy of wind to mill grain, often contained in a large building as in traditional post mills, smock mills and tower mills.
Windmills were developed from the 12th century, apparently from technology gained by crusaders who came into contact with windmills in the Middle East.
The development of the water-pumping windmill in the USA was the major factor in allowing the farming and ranching of vast areas of North America, which were otherwise devoid of readily accessible water.
