A Pb-Zn mine.


To the south of Glogfwar Mine the site clings to the steep hillside which is covered in spoil. On the level ground there is one deep shaft to the east and a ditch presubaly for flat rods connecting to the foundations of ruined buildings in the south quarter of the site. The main notable feature is however a large section of clear and well preserved cobbled dressing floor.

At the foot of the hillside is a track and then an area of rough apparently marshy ground with a spoil heap from the level shown to the south-west on the Ordnance Survey plan.
