Where is the worst place in the UK that you've visited?

This is actually a hard question. I can't really think of anywhere that's truly terrible so I'll have to throw a few caveats around. Whitechapel/Shadwell seems very dirty, seedy, smelly and run down for somewhere so near the City where you can buy a flat and not see much change from a million quid. Or you could spend less and run the gauntlet of not getting stabbed on your way home from work. Ive stayed there quite a few times as it's cheap, and it's easy to see why it's cheap... Coventry seemed incredibly bleak when I went to a uni open day years ago, yes I've judged it based on a fleeting visit. People talk about places being grey, I've never seen anywhere as grey. Lands End is a sort of... "Is that it?" place that takes ages to get to, has some very random commercialised bits, very windy (which to be fair is to be expected). Other than going to say you've been, I don't really see the appeal.
