Mystery Stone Blocks

During excavation work to repair the broken pipe that returns collected water from the waterwheel back to the mill pond, some stone blocks were discovered. They were located in the mill yard in front of the left side of the mill cottage and at a depth of approximately one metre.

The blocks are sandstone and have groves chiseled and drilled into the top surface, the purpose of which is unknown. Could they have been foundation blocks of an early mill with wooden walls located in the groves?

The blocks are now located in the Cart Shed to view and wonder at their original function.
