As far as getting permission goes, I suppose it's a case of how much kit is involved. If you show up bristling with gear then someone might have something to say, mainly because these days the Health and Safety aspect is what they are largely concerned about, ie someone tripping over a tripod leg and going a*s over t*t down their forty foot flight of 14th century granite steps! I rather like the old maxim "Tis far, far easier to beg forgiveness than to seek permission."

I sense you're ahead of me here ... and if you go up them there are superb views across the meanderings of the Wye to the Severn and the Severn Bridges.
