Could you help turn an entire windmill?
Bourn Windmill is one of England’s oldest surviving windmills and a designated Ancient Monument. Built during the reign of Henry VIII, it is also one of only around 50 trestle post mills still standing in the UK.
Unlike later windmills, the whole wooden body of a post mill must be turned so that its sails face squarely into the wind. It sounds like an impossible task, but just two or three people can rotate the entire structure around its central post.
At our August Open Day, our knowledgeable volunteer guides will welcome you inside, explain how the mill works and share the story of this remarkable building, including the essential restoration work that allowed it to reopen in 2023.
