National Mills Weekend – May 13-14, 2023

People all over the U.K celebrate National Mills Weekend every second weekend of May and this year it will run from May 13 to 14. This annual festival is facilitated by the Wind and Watermills area of the Society for the Protection of Ancient Buildings (SPABs). On this weekend, numerous protected wind and watermills — which are often closed to the masses — open their doors and offer some knowledge into the process, workings, and history of the mills.

History of National Mills Weekend

National Mills Weekend is an event in the U.K. that took place initially on the second Sunday in May. What started as a single-day occasion later extended to include Saturday and is presently known as National Mills Weekend.

The first evidence of a wheel driven by water appeared in the technical treatises of the Greek engineer Philo of Byzantium who lived between 280 B.C. and 220 B.C. Later on, during the seventh century, watermills became well established in Ireland and a century later, they spread into Germany. In 1870, two-thirds of the power used by the British for grain milling came from watermills. In the nineteenth century, there were over 20,000 watermills in Britain, and they were used for grinding bones for fertilizer, paper manufacture, powering forge hammers, etc. They however became obsolete in the early twentieth century due to the availability of affordable electrical energy.

National Mills Weekend is aimed at bringing the attention of the public to the importance of making repairs and protecting traditional mills so that they can be kept in good working conditions. National Mills Weekend’s official website supplies information yearly about the watermills and windmills that would be open to visitors. This is because these mills are usually closed for their preservation but are opened on National Mills Weekend for excursions that give people insights and knowledge about the history of the mills.
