Its current owners market the castle as being the most haunted castle in Britain.
It has been investigated on television, Most Haunted, I'm Famous and Frightened!,
Scariest Places On Earth, Holiday Showdown, Alan Robson's Nightowls), The ParaPod, Ghost Hunters International, and A Blood Red Sky (2013).
 Some of these ghosts are referred to in a 1925 pamphlet by Leonora, Countess of Tankerville.
Others, such as John Sage, are of more recent invention.

The most famous ghost of the castle is the "blue (or radiant) boy", who according to the owners used to haunt the Pink Room in the castle.
Guests supposedly reported seeing blue flashes and a blue "halo" of light above their beds after a loud wail.
It is claimed that the hauntings ceased after renovation work revealed a young boy inside a 10-foot-thick (3.0-metre) wall.
Documents dating back to the Spanish Armada were reportedly also found within the wall.
