Well...I tried today and failed miserably. Found a decent gap in a fence but I'm a bit on the chunky side to get through without needing a tetanus shot afterwards...may need to try again with a friend to help haha
No worries. Allow yourself plenty of time. Its pretty big. Don't forget the brown building across the way either. Some of the wards get a little repetitive but its still all good. The basement has some cool bits to see too.
Thats the Sessions House. The last time it was used it was a carvery. It sucked but damn what a gorgeous building inside and out. It is in fact closed down and unused now. I'd love to get in but unless i'm breaking through a window or door, its pretty impossible. :-(
