We took a run out into the English countryside recently to visit the beautiful Pitstone Windmill, which dates from the 17th Century (visitors can see the date 1627 carved into a wooden beam).
Now belonging to the National Trust, the design of the mill is what is known as a post mill, which means the whole superstructure of the mill rests on one main post. This post rises 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.
Given when it was built, the windmill is an engineering marvel. In a time where the majority of Britons couldn’t read or write, that there was someone who could imagine, design and built such a structure is mind blowing.
