Arundel Castle in Sussex is often said to be home to just four ghosts but there are more ghostly goings on between its ancient walls than first meets the visitor. The spirit of the first Earl of Arundel, who originally built the castle, is said to still haunt the Castle's Keep. Another spirit is said to be of a young woman who, stricken with grief from a tragic love affair, took her own life by jumping to her death from one of the towers. Seen by some, she is said to still haunt the castle on moonlit nights dressed in white. Another spirit is that of a 'Blue Man' who has been seen within the library since the 1630s and it is thought that he could be a Cavalier due to his time period seeming to be from King Charles I's reign. Another notable 'spirit' is that strangely of a white owl like bird. Legend tells that if the white bird is seen fluttering in one of the windows, it is an imminent warning of a death of a Castle resident or someone closely associated. It's interesting to note here that Dukes used to keep a colony of white American Owls here at the castle before its restoration. There is also mention of a servant lad who once lived at the castle who was treated very badly until beaten to his death. He is said to now haunt the kitchen area and has been seen scrubbing pots and pans. Another strange sighting was more recent in 1958 by a footman. Working late one night on the ground floor the footman was walking near the servant's quarters and saw what he thought to be a man walking in front of him when he thought he had been alone. As he got closer to the apparition the man faded and then was gone.
