Coventry.
I installed one of the floodlights in the ruins of the old Coventry cathedral. A friend had the job with two colleagues and the one that could drive was off, so I got roped in for that day. It is set in the ground, where the bloke in the turquoise shirt is, in the far corner, here.
I remember looking up at the remaining stonework and thinking that some of it looked very ropey. About a fortnight later, one of the pinnacles blew down, just where we'd been working. Missed the light, though...
