It has been visited by numerous paranormal investigators and psychics. It has also been used as a filming location. 

Lord Byron held many parties here. The last private inhabitant was Colonel Howard-Bury (1883-1963), who inherited the castle from his mother. He was a British soldier, explorer, botanist and Conservative politician. He preferred, in later years, to live on his other estate Belvedere House (see: http://www.belvedere-house.ie) and on his estate in North Africa. Today the estate is managed by the Charleville Castle Heritage Trust.
