A derelict shop on a main road in Nottingham.
By pure chance the door had been left open. Very small and the ceiling seemed fairly unstable. Completely infested with rats (You could see the ceiling was unstable as the rats ran across above.) Has an upstairs but did not venture as the daylight was fading, a police car was waiting outside and of course - rats.

The shop next door has been almost entirely demolished and workmen are there during the day. Some interesting walls left standing and pieces of machinery left around though.
