Bourn Post Mill

One of the oldest surviving post windmills in the country, and a Scheduled Ancient Monument. Working until 1926 and gifted to Cambridge Past, Present and Future (CambridgePPF) previously the Cambridge Preservation Society in 1932. The mill has been lovingly restored by CambridgePPF. It dates back to at least 1636, although it may be much earlier.

Bourn Mill provided inspiration for the work of one of our most eminent contemporary architects. Lord Foster prepared drawings of its elevations whilst studying architecture at Cambridge.

An open trestle post mill. The sails of the mill (two common and two patent) have to face squarely into the wind and to achieve this the entire mill is rotated around the central post.

Opening times - see calendar: To see all events, pull the scrollbar down and up several times or press "look for more" repeatedly.

The exterior of the mill can be visited throughout the year.
