In reply to pancakeandchips:
This has reminded me of the Stourbridge Crystal Leisure centre wall, which is in a converted squash court. Used to climb there loads, really unique old-school wall. The panels, which I think are fibreglass with sanded paint on for texture, were great, I particular it had the best indoor slab I’ve yet to climb on. Some of the eliminate routes (like the 50p sequence) were utterly desperate. The main walls had inset bit of rock, which I think were actually slate, glassy as anything but great fun. Somebody broke their ankle i think and that set in train the non-climbing management shutting down access except to their own courses, and I believe some unredeemable heathen bolted on obtrusive, massive plastic holds all over the walls. Utter desecration. I also remember somebody had graffitied ‘This is my church, this is where I go to heal my hurts’ on the ceiling. Simpler times.
Edit to add a link so you can see the full horror of that butchered slab:
