Jordan,T. (1910) Abergavenny Chronicle, March 18: Reminiscences of the Old Clydach Iron Works and Neighbourhood "Not far above the Black Rock falls are the springs called Ffynon-ish-faen, which means, in Welsh, the well under the rocks. There are several strong springs gushing out from under the banks on either side of the river, which are said to be always of the same temperature and volume all the year round, and to each separate spring is attributed some special medicinal virtue."
