This is the north mill, built in the late 18th century when the site changed from corn milling to flint milling.
From
Link we are informed that Cheddleton Flint Mill consists of a complex of buildings including two separate water mills, a miller's cottage, two flint kilns, a drying kiln and outbuildings. The Caldon Canal, which would have supplied the mill by narrow boat, passes nearby.
Also, it is known that milling at Cheddleton dates back to 1253. The foundations of the South Mill may date back to this period. A 1694 reference mentions corn milling at the site.
