The old water powered mill at Boot in Eskdale does function during the warmer part of the year, but as a 'living museum' feature.
The circular stones that you see in the picture are worn out grinding stones taken from the mill. They reckon to get about 20 years from a stone set and the lower floor is paved with discarded ones!
"It is not known when milling began at this place but it may be as long as 3,000 years ago when the forests were cleared and cereal crops were first grown. The mills recorded history starts in 1294 with an entry in estate records "...all the mill of Easkdale which renders 19s 6d yearly". The mill stones found around the site and even laid in the floor of the mill are estimated to represent at least 700 years worth of milling."
