Crumlin Road Jail - now a tourist attraction!
Read more about the history of the prison here - http://en.wikipedia.org/wiki/HM_Prison_Crumlin_Road
This photo is of the tunnel which runs under the main road direct from the court house which is now standing derelict after a major fire in 2009 - read more about that here! http://en.wikipedia.org/wiki/Crumlin_Road_Courthouse
Allegedly.....possibly quite understandably the tunnel has the ghost of a former warden who died in the tunnel - glad the lights were on!
