Bourn Windmill is a post mill, the earliest known surviving example of its type, believed to date from the 14th century. The mill stands on its original site in the village of Bourn, Cambridgeshire, and represents a significant development in medieval milling technology, with the entire wooden superstructure capable of being rotated to face the wind. The structure has been substantially restored and preserved, retaining essential features of post mill construction including the main post and supporting timberwork that characterise this form of vertical axis rotation. As a rare surviving example of early post mill engineering, it remains an important monument for understanding the development of wind power technology in medieval and early modern England.
