There is an old castle in Norwich which is believed to be haunted. It is called North Castle and it is said that ghosts can be seen there at night. The castle was built 400 years ago and was owned by two old ladies who are believed to be witches. One day, long ago, they both disappeared and were never seen again. In 1985 the castle was bought by a businessman and converted into a luxurious hotel. The castle is visited by quite a few guests every year and special groups are organised to watch for ghosts. It has been a long time since any ghosts were seen, but one night a trick was played on some visitors by a local couple, who dressed up as the two "witches". They were seen by a guest, who said she was frightened almost to death. The couple apologized the next day, and were told never to visit the castle again, certainly not in the middle of the night dressed up as witches.
