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

The next National Mills Weekend will take place on Saturday 8 and Sunday 9 May 2027.

Across the country, hundreds of mills – including some not normally open to the public – will be taking part.
