Bourn Mill is a nationally important piece of our industrial heritage. It was purchased and saved from dereliction in 1932 by the charity Cambridge Past Present & Future and since that time has been repaired many times, most recently in 2020-23.

It is a remarkable survival, the central post of the mill dates to the early 1500s making it the oldest in England, and is one of only 50 post mills left in the UK.

The mill inspired the UK's most famous architect, Lord Norman Foster, who says:

In an age when we are reminded that innovation and design are key to critical need to reduce the effects of climate change, it is only right that we are afforded the ability to look back to an age when we were undoubted leaders in such innovation.

Bourn Windmill is designated as an Ancient Monument and like many ancient buildings, it needs constant repair and maintenance from specialist architects and craftsmen, which is often expensive. Our charity receives no regular funding from local or national government, so the care and repair of this important historic building and machine relies on people like you, so that it can continue to be enjoyed by future generations.
