 There had been moments of industrial strife, notably the 1926 general strike and the ‘stay in’ strikes of 1935.In 1954 the National Coal Board merged the two pits, and finally in 1966 after a hundred years of production the Parc and Dare pit closed for the last time, leaving Cwmparc’s ‘sylvan’ valley to revert, in some measure, to its original beauty.On the night of 29 April 1941, during the Second World War, Cwmparc was bombed by the German Air Force.
