Wicken also has the last 12 sided Smock windmill of its type still working in England which has been restored to full working order by an enthusiastic team of volunteers. The mill produces wholemeal flour, white flour, finest white flour, wholemeal and white Spelt and rye, all grown without the use of fertilisers and milled using only windpower driving two sets of burr crystal mill stones. The mill is open during the first weekend of every month and whenever the sails are turning. Entry is free, see Wicken Windmill on Facebook for more information.
