They start at St Marys Hospital but where they lead is a mystery. Rumored to lead to the Magazine fort whether its true or not god only knows! Any information would be great.v July 3, 2009 at 9:10 am #808123 AnonymousInactiveSt Marys used to be the Royal Hibernian Military School. Would that be a reason for them to lead to the Magazine Fort?
