Muncaster Castle is reputed to be one of the most haunted castles in England. Tom Skelton was a jester in the 1500's and was a force to be reckoned with in life and now, it seems, in death. The legend is that when travelers would stop at the castle and ask for directions to London - if Tom didn't like them, he would send them in the direction of nearby quicksand and marshes - to their death. He also chopped the head of off the local carpenter because Sir Ferdinand Pennington asked him too as the carpenter was in love with Sir Pennington's daughter. I've attached a portrait of Tom that still hangs in the castle.
The most haunted room is the The Tapestry Room. Many people complain of strange footsteps, a child is often heard crying and a lady singing. People often feel cold in this room and have the sensation that they are being watched. There is also a ghost of the Muncaster Boggle or White Lady who haunts the gardens and local roads, she is supposed to be the ghost of Mary Bragg who was murdered in the early 1800's.
The other night I watched a programme on National Geographic channel called Hauntings, and Muncaster Castle was featured. There has been a parapsychologist investigating the castle for 6 months. He said that the bed in the Tapestry Room is unusually made of something like iron coils I think they were, it was like a springy chainmail. He said the magnetic field around the bed was bizarre and showed how oddly a compass reacted to the bed. His theory was that some sensitive people might feel odd sensations around the bed and this could be why they feel the room is haunted. Interesting stuff.
