Description

Old Gang Smelt Mill is a lead smelting mill, along with its flue and subsidiary buildings, dating from the late 18th century to the early 19th century. The structure is built of coursed rubble. An earlier building complex is located on a terrace to the north of the later buildings, which sit in the valley bottom. The layout of the earlier mill is not clearly defined. The later mill features a main building with a wheelhouse on the left side, and to the right, there is a slag hearth and three ore hearths. A separate building to the right contains a roasting hearth, while the building at the far right has a former silver hearth. The flue connects the ore hearths to the older mill and extends up the hillside to the remains of a chimney. At the time of the resurvey, the buildings were in a ruinous state but still standing in places up to roof height. The tall square section chimney associated with the silver hearth remains intact. The site is also designated as a Scheduled Ancient Monument.
