Mills Open Days Start on National Mills Weekend 2026

Two Mills, One Living Landscape

This May, two of Cambridgeshire’s most distinctive heritage sites reopen their doors.

Across National Mills Weekend, 9–10 May, Bourn Windmill and Hinxton Watermill mark the beginning of their 2026 open season, inviting visitors to step inside these working structures.

At Bourn Windmill, one of the oldest surviving post mills in England, everything is driven by air. The height of the sails and the movement of timber and gears reflect a world powered by changing weather and physical labour.

At Hinxton Watermill, the energy is steadier. Set beside the river, the turning wheel is shaped by the continuous flow of water. The experience is quieter, but no less powerful, a reminder of how closely daily life once followed the rhythms of the natural world.


More than preserved buildings

Both sites are cared for by Cambridge Past, Present & Future as part of a wider commitment to protecting the region’s heritage and green spaces.

These mills are not static exhibits. They are working reminders of how communities sustained themselves, through skill, resilience, and a constant negotiation with the elements.

To stand inside them is to feel that reality more directly, the scale, the movement, and the ingenuity required to make it all work.


Opening weekend: 9–10 May

A different way of seeing Cambridge

Cambridge is often understood through its architecture and academic history. But beyond that lies another story, shaped by land, weather, and work.

These mills offer a way into that story.

This season, the invitation is simple: come inside, and see how it worked.
