Inside the galleries the scale doesn't diminish - massive walls hundreds of feet high, columns of stone, tunnels disappearing into darkness. But walk through Dinorwig fifty years after closure and what dominates is colour and quiet: turquoise pools between slate, yellow lichen, moss reclaiming the carved walls, ferns and a solitary tree on piles of waste. The site was shaped by thousands of workers extracting slate for a century. Now it's being remade by water and moss. I was comparing how a massive industrial space transforms when humans leave it - the scale still there, but the purpose entirely altered.
