This converted farm has eight old mill stones built into the wall that runs along the road outside. This is the first millstone next to the gate and shows a monolithic stone i.e. the millstone is made from one piece of stone. Stones like this were made to the correct shape at the source quarry and were transported to the mill where the millstone dresser would cut the furrows in the stone that would give the stone its grinding action. This particular stone appears to be made of millstone grit from the peak district area of Derbyshire and Yorkshire. the closest mills to the farm are on the River Windrush, one is at Aston farm at SP 1497 2134 and the other at Bourton on the Water at SP 1631 2082. Whether these stones came from either of these mills or elsewhere is unknown.
