MR would probably enjoy this. A Haunting at Preston Castle was filmed there. So, was The Apparation. The T.V. shows the "Ghost Hunters" and "Ghost adventures" also investigated it. They have a haunted house during Halloween and guided or self-guided tours. You can also stay the night. Well, at least from 7:00 p.m. until 2:00 a.m. where you can join a paranormal night tour.
