Description
Close to the road is a built-up platform with heavy stone retaining walls and a level, paved surface, on which probably stood a slate processing mill of wooden construction. At the north-east end is a waterwheel pit which could have accommodated a waterwheel 35ft (10.3 metres) in diameter and 5ft (1.5 metres) wide. A covered channel under the floor probably housed a shaft transmitting power to machines above. At SH5203544324 is a small reservoir excavated in the bed of a narrow rocky ravine.
