Welcome to the website of Jack and Jill Windmills Society.
Our Society, a registered Charity, has fully restored and now maintains Jill Windmill - a 19th century corn windmill located at Clayton, West Sussex in the United Kingdom. She is a traditional working corn windmill in the South Downs National Park.
The vast majority of the restoration work and the ongoing maintenance of Jill Windmill has been carried out by unpaid Society Volunteers, who have met at the Mill on virtually every Saturday since January 1979.

In May 2008 our Society was awarded a plaque by the SPAB Mills Section. This is the second major award presented to our Society in recognition of our restoration and maintenance of Jill Windmill. Click here for details
In April 2011 we painted the exterior of Jill Windmill using volunteer labour, as part of our seven year cycle of maintenance work. Click here for details.
Jill Windmill has been restored to working order and she now produces stoneground wholegrain flour on an occasional basis. The vast majority of her flour [which is sold to visitors] is ground from local wheat, grown in Sussex.

Our Society's own publication "Clayton Windmills" is on sale at Jill Windmill on Open Days together with mill information sheets in English, French, German and Czech.
The publication is not available through bookshops, however copies are available by mail order.
With spectacular views across the Sussex Weald, Jill Windmill and her site have proved to be very popular locations for both professional and amateur photographers. She has also been frequently used as a backdrop of wedding photos and wedding blessings.
Jill Windmill is owned by Mid Sussex District Council. The Council has made and continues to make significant financial contributions towards our work on Jill Windmill.
Over the years Jack and Jill Windmills have been used as television, photographic and film locations.
Jill, along with her neighbour Jack (in private ownership), stand atop the scenic South Downs with spectacular views of the Sussex Weald. The windmills are seven miles north of the city of Brighton and Hove.
When the wind is blowing (as it frequently does on the South Downs) Jill may be in operation and a guide available to explain the mysteries of milling. Whether you drive up to see us and enjoy a picnic or drop in as part of a long distance walk along the Downs you will have the opportunity to step back more than one hundred years into a working windmill.

On 9th May 2009, for the first time in over 100 years, the sweeps of Jill Windmill and of Oldland Windmill were turning in the breeze. On 10th May 2014, both windmills ground flour on the same day.
