I definately should have tried harder while I was over there as it looks mega, but post night shift with a ferry to catch I only managed a brief hop over the wall and a bit of a wander round the outside!
There’s a lot to see here if you look long enough. It’s not the easiest to access at the moment but is totally worth the effort. There are still a few buildings I couldn’t gain access into making another trip worthwhile. There is somewhere else I must check out half way there so it’s a good enough excuse for me.
