Llwyn Madoc

Llwyn Madoc lies in the community of Glascwm in the county of Powys. It is located at Ordnance Survey national grid reference SO08505515. The mine is recorded in the CPAT Historic Environment Record as number 18975 and this number should be quoted in all correspondence.

Coal trials (1816)

Silurian shales altered by igneous intrusion.

Workings are mentioned in Williams (1904) but these could not be located during the site visit. A small quarry on Castle Bank displays the favourable geology for a coal trial and it is possible that the quarrying destroyed earlier openworkings.
