Is it the one in St. Peters Square along the Town Hall extension?
It's absolutely disgusting, the tents are in a line against the covered walkway, at one point there were two rows, there is also temporary fencing to stop them accessing the walkway on which they hang their clothes with rubbish and half eaten takeaway food just strewn behind the tents, it's been there for quite a while, they were dispersed for Remembrance Sunday and again for New Year, they set up around the Midland hotel for those two occasions but they have returned.
