Not a Military Barracks. This ruin was home to the miners who worked the slate quarry at Cwmorthin. Only ar weekends would they make the descent to the village. although there was a Chapel in the quarry, so the workers could remain in the Barracks ad infinitum. In winter the ascent would have been almost impossible, if conditions became too frozen. I climbed this slope three years ago, and I had to 'traverse', the path to lessen the incline! Good shots up there though. It's largely a man-made scene, but none the less magnificent for all that.
