CILFREW COLLIERY The Cilfrew Colliery Company opened the Cilfrew level here in 1913 and by 1924 had 252 workers. The mine workings extend into Craig Gwladys mountain as far as the Cwmbach road (the road you walk down by the golf course). A dram road was constructed to join up with the old Torcefn dram road. The mine closed in 1932 because of rising water levels.
