Visited with Aragorn777 and as KingElvis observed, it's pretty much all ripped out. However access can now be gained to most of the buildings. There's a lot of pidgeon crap, a few bats and we saw the back end of a retreating cat! One nice find, though, was a colourful mural of tropical fish in an upstairs room. A housing estate is encroaching and there are machines on the site; at least 2 buildings visible on Google have now disappeared. Still, it was interestingly laid out and we found it quite atmospheric. Photos ready to post....
