We went today for the first time and agree it's extremely easy to access.
No security, no police.
Potentially squatters though - on 3rd floor of the front main building a room has been set up like a bedsit, with a double bed, a couch & some chairs! Plenty of cider bottles/cans etc in that room and the two around it. Further on to our explore we bumped into a man & woman wandering round with cans of lager, but they didn't seem keen to hang about with us !
