Chilling by name, chilling by nature, Chillingham Castle in Northumberland is regularly declared the most haunted castle in England and as a result has drawn many TV 'ghost hunting' programmes to film here including Most Haunted. The castle's most famous ghost, a young boy, was documented by Leonora Tankerville, the lady of the house, in 1925: With a turbulent military history dating back to the Elizabethan period and running right up until World War II, Pendennis Castle in Cornwall has accumulated its fair share of ghostly tales.
