I went to explore St Thomas hospital last month in Shaw heath, Stockport. It was a great place with plenty of history and you could see the story's and history from the finds. It has now become a commercial hotspot for chavs and vandals that just want to smash shit up. other than this its a decent explore with my advice of exploring on a Sunday when the college isn't active . They use this space as a car park for the staff of the college so best to do visit when thats not the case.
