Constructed in 1070 and later slighted during the English Civil War, this ruined fortress is dominated by the legend of the “Grey Lady,” believed to be the spirit of Dorothy Beaumont who died in 1646 after her newborn child perished. Witnesses frequently report a sorrowful figure in a grey gown wandering the chapel undercroft and the Grey Lady Tavern, often accompanied by a blue mist, sudden temperature drops, and the sound of a “screaming child” echoing through the stone corridors. The castle keep is another major hotspot where people have heard the rhythmic beating of a drum attributed to a young “Civil War Drummer Boy” killed by a musket ball, as well as sightings of an elderly woman with a black cat who was purportedly executed for witchcraft on the battlements. Modern paranormal investigators and zoo staff have documented poltergeist activity in the aquarium area, including doors slamming on their own and visitors reporting the sensation of being prodded or having their clothes tugged by unseen hands.
