Access to this place was something of a community effort. (Usually talking about such details for all to read and pass around would be sort of an offence in the exploring community but the building is no longer with us.) A ladder presumably found on the grounds elsewhere was kept in the overgrown area behind the buildings, safely stored by one explorer ready for the next one trusted to visit the place. A great agreement as long as somebody doesn't trust the wrong type of explorer to visit next. Using the ladder to get onto the roof, the skylight opened and you could simply drop down onto the 'body fridges' in style. Luckily no vandals had been inside before me and all the decay was completely natural.
