Reported spectral tenants include the cantankerous "Mr. Boots", who nudges tourists, can be heard swearing, and tails tour groups while clomping on the stone floor. Then thereís young "Jack", a boy who giggles as he runs about the dark rooms. Tours include your own electro-magnetic field recorders that allow visitors to measure the effects of the Vaultís ghosts. An area in the rear corridor near Room 8 is frequently pinpointed as a hot spot of strong spectral activity.
The frequent reports of paranormal activity and ghost sightings resulted in the top UK paranormal investigation show, Most Haunted, to investigate the vaults in both a 24 hour investigation and for a Most Haunted Live show on Halloween 2006.
