This is the Tolbooth in Edinburgh. It was once a prison but is now a museum and a very spooky museum at that. There is a guided tour complete with sounds and smells of a past age when it was a prison! And at the back is a graveyard of previous inhabitants.
There is even a grave complete with resident ghost. Unfortunately I have never seen it but several say they have! Spooky! Lovely mausoleum though!
