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 BN6 9PG 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. Click here for our Trustees Report.

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.

This website has a Mobile Friendly page with historical information together with details of Open Days at Jill Windmill and her location. Please click here.

Our Society has been awarded a plaque by the SPAB Mills Section. That was the second major award presented to our Society in recognition of our restoration and maintenance of Jill Windmill. Click here for details

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, Russian 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 for 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 walk along the Downs you will have the opportunity to step back more than two hundred years into a working windmill.

Jill is taking part in a technology trial, aimed at monitoring windmill movement with digital compasses. The system takes frequent compass bearings of the direction of the Sweeps and compares these to wind direction, both actual and forecast. Click here for further details.

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.

Is Hassocks the only village in England with two working post mills ?
