Chillingham Castle
Chillingham Castle in Northumberland has a reputation for being one of the world’s most haunted and most terrifying castles.

Several ghosts are said to reside here, the most famous being “the Blue Boy,” who haunts the castle’s Pink Room. At the stroke of midnight, cries of terror and pain can be heard emanating from a passage in the wall. When the cries fade, it is said that a halo of blue light would appear and the figure of a boy in blue would approach the bed. During a refurbishing of the castle, bones of a boy along with fragments of a blue dress were found in the wall.
Another ghostly resident of Chillingham is the ghost of Lady Mary Berkeley. It is said that you can hear the rustle of her silk dress as she walks the corridors in search of her husband, who ran away with her sister.

Chillingham is also said to be haunted by the infamous torturer John Sage:
“It’s the home of the torturers. 97% of everybody who went into that castle didn’t come out. It’s a horrible killing machine.”
