Lacey Green Windmill, which is open on Sunday and Bank Holiday afternoons (2 - 5), from the beginning of May until the end of September.
Described as England's oldest Smock Mill, the windmill has been carefully restored and preserved by members of The Chiltern Society and is staffed by volunteers. Entrance is £2 for adults and £1 for children (5 to 15).
Without the ability for the cap to rotate to face into the wind, the windmill could get seriously damaged in a strong gale.
The sails at Lacey Green generally only rotate properly, with sailcloths, once a year during National Mills weekend. This year it was on 15th May and in 2012 is planned to be on on 13th May. A full description of this year's event may be found here.
Access to the mill is gained down three steps and then up from the ground floor to three further levels via some rather steep wooden ladders. For obvious reasons, the inside of the building is most definitely not wheelchair accessible. Indeed access will be seriously inhibited for anyone with mobility problems.
The windmill is not overly commercial - the prices are refreshingly good value. There is no gaudy tea room (though there is a nice looking pub at the end of the access path) and the choice of souvenirs is rather nicely limited.
Lacey Green Windmill is about local people caring for a really rather nice piece of English heritage. Don't travel hundreds of miles to see it, but if you happen to be in the area when it is open, please do visit it - England is all the better for having fascinating buildings such as this and a short visit is thoroughly recommended.
The windmill contains a hugely informative set of displays, setting out the historical context of the building. I had never really given much thought to the location of windmills and water mills in the area. I can however guarantee that if you visit this piece of history, you will learn something.
Lacey Green is a couple of miles South of Princes Risborough. It has a reasonably good bus service and excellent travel directions are provided on the windmill's highly informative website. Recommended.
