National Mills Weekend is an annual celebration of windmills and watermills, promoted by the Mills Section of SPAB.

National Mills Weekend 2026: 9 & 10 May

Across the country, hundreds of mills – including some not normally open to the public – will be taking part. The next National Mills Weekend will take place on Saturday 9 & Sunday 10 May 2026.

Mills Now and Then: Call for Contributions

To celebrate mills in 2026 we are producing a compilation of individual mills' histories, and we would like your help. The SPAB Mills Section wants to create a new and comprehensive picture of mills of all types throughout the UK and Ireland.
