Keston windmill was built in 1716 and still stands on the edge of Keston Common overlooking the vale of Keston. The mill is a 3-story black weatherboard wooden structure resting on a round brick base and built on high ground, over 450 feet above sea level. It is a 'post mill' type, with the structure tied to a central massive wooden post that allowed it to be turned as the direction of the wind changed.
