2. Glamis Castle – Angus, Scotland
Built in the 14th century, Glamis Castle has a plethora of ghoulish legends attached to it. There’s allegedly a secret room where a horrifically disfigured child was hidden from sight after being born to the 11th Earl of Glamis, and in other stories, the secret room was used to hide the bodies of enemies of the Glamis clan. Another tale says the secret room served as a location for a card game with the devil himself. The spirit of Lady Janet Douglas, who was burned as a witch in 1537, is said to haunt the castle’s chapel, and there are various other tales of ghosts that haunt the castle.
