Castle Mill

Castle Mill is a former spinning mill and adjoining cottage, now converted into three houses, built around 1783 and remodelled around 1960. It was constructed by the Robinson family and features coursed and squared rubble and dressed stone, with concrete tile and slate roofs. The building has a partial rubble plinth, a crenellated parapet, and a single coped gable. It stands two storeys high with a basement and has six unequal bays.

The north front includes the mill building, which has two square crenellated corner towers, each featuring two blank roundels and a quatrefoil above. To the left, the basement has a blocked door flanked by single casements, and to the right, there is a door. Above, there are five casements on each floor. To the right, a 20th-century door with a hood is present, along with two casements above it. The cottages to the right have a casement flanked by a door on the left and a French window on the right, with a lean-to hood. Above this, there is a large square bay with three casements, flanked by two smaller casements.
