In connection with this, members may be interested about a Dolwyddelan Historical society talk next week about Cwmorthin (the cwm, not specifically the quarry).
Date: Monday 3 February, 7.00pm
Venue: Dolwyddelan Community centre (opposite the railway station)
Speaker: Mel ap Ior Thomas
Please note I have no connection with this, I'm just passing on the information.
