Description

The north-eastern aerial ropeway revetment, incline, and associated buildings is a large structure resembling a ziggurat, made of sawn slate blocks and oriented roughly east-west. The sides of the structure are significantly battered, featuring offsets on the north face. At the southern end, there are remnants of slate-built structures on top. Extending from the south end in a north-westerly direction is a slate-built inclined plane, which includes the remains of a winding house at its upper end.
