The Tonypandy riots of 1911 happened during a miners' strike/employers' lockout over pay. In fact most of the clashes between soldiers and miners happened in Porth. The troops did not open fire, but one miner died, probably as a result of a blow from a police truncheon.
From Mynydd Rhiw in Aberdaron parish it is said to be possible to see the Wicklow Mountains in Ireland on a clear day.
