The trip is built under Nottingham castle in caves found there. Legend has it before the Crusades, men would gather there before leaving for the Holy Land. The staff are always very friendly and if it is slow you can ask for a tour of the caves they use. They have a large wood Galleon that is kept tight under a glass frame. Covered in dust and suspense, anyone that touches it will die. The last few people that HAVE touched have in fact perished in strange and sudden ways.

There are a few other pubs of interest in the near area including the Ye Olde Salutation Inn (c.1240) that is haunted by a 4 year old ghost within easy walking distance of the Trip.
