The cutting shed at Dinorwic slate quarry in North West Wales. Probably the best surviving example of its time, the equipment has been left to the forces of nature on the higher levels of the quarry for half a century since this mammoth site closed. Slabs the size of men would be transported here by the quarry's own railway to be split into thin segments by hand before being trimmed by rows of circular saws. Put into batches, it would be sent down to the lower levels and transported across the country ready for use, at a time when it was still recognised as the most durable roofing material in the world before cheaper alternatives entered the market. Work here only ever stopped for lack of daylight, and the men were paid very little despite the dangers of their work. It truly is one of the most fascinating places to walk through
