Overview
On a cold, wet day, Len Vaughan Williams – an electricity board employee and later deputy head of Bangor's Ysgol Cae Top primary school – took his camera to Dinorwic Quarry, anxious to capture some footage for posterity (e.g. blasting, transportation, dressing and splitting) as the writing was on the wall - closure was effected in 1969. A handful of men can be seen at work, their number as nothing to the 3,000 that would have been employed during the quarry's heyday.
After closure in 1969 the quarry buildings became the National Slate Museum (part of the National Museum Wales) and the quarry itself houses a pumped storage power station.
