Partly underground working.*

Series of three distinct levels connected by engineered tracks, reflecting the original internal layout of the workings. On the upper level, the rock appears to have been worked from below, and several small buildings remain, including a distinctive circular powder house. The intermediate terrace contains a large excavation entrance, a short side tunnel, and the remnants of two dressing sheds where material was once processed. The lowest level preserves a collapsed tunnel along with fragmentary remains of what is thought to have been the mill.

partly underground quarry, supplemented by a small mill that likely handled basic processing of the extracted stone. By 1896 it was already recorded as disused.
