Bourn Windmill dates back to 1636 and is one of the oldest windmills in England; it is designated as an Ancient Monument. It is known as an open-trestle post mill, one of only seven remaining in the UK, because the main mill (the “buck”) is balanced on a “post” supported by an oak trestle, which is mounted on four brick piers. This allows it to be rotated such that the sails face squarely into the wind. Although the sails still turn, they do not grind grain. The mill ceased operations in 1926, when it was sold.
