Bevan, G.P. (1856) On the Geology of the Beaufort and Ebbw Vale District of the South Wales Coal-field, The Geologist 1(2), pp.51-52: ..."in a small cavern to the east of the [Trefil] quarry the walls are of limestone, while the roof is of grit. This cavern was turned to good account by some blacksmiths at the time of the Chartist insurrection in 1839, and used as a place for making pikes and other weapons."
