A 220-year-old Grade II listed windmill in Derbyshire has been broken into and had an Heage Windmill in Belper overnight by forcing their way through the west door.
Thieves got into Heage Windmill in Belper overnight by forcing their way through the west door.
The mill was damaged as well as the undercroft, where there are displays explaining the story of the mill.
The Heage Windmill Society is particularly upset by the theft of one item - a mill bill used to sharpen the millstones.
Not only is the society "distressed" by the loss of the 150-year-old tool, it is also concerned it could be a "potential deadly weapon". It had been chained down at the mill.
Those behind the break-in even left their stamp on their crime by scrawling in the visitor book.
The society has said steps have now been taken to secure the windmill and further safety measures will follow.
