#KilveyHill, Swansea has a thousand year history of coal mining.Swansea was a coal town,even the Romans and Vikings would have burnt local coal.This mine on the Hill shut down in the1700s.It was on the Swansea 2ft Seam.The exposures can still be seen and the entrance to the tunnel is in the centre.The rocks show destructive effects of centuries of copper smoke and sulphuric acid.
