Lady Olive Baillie, the last private owner of Leeds Castle, who dedicated much of her life to restoring it to its former glory, is believed to linger as a benign spirit. She died peacefully in the castle library in 1974. Her apparition is described as an elegant woman dressed in 1930s evening wear, consistent with the period she most actively hosted lavish parties and events. She is often sensed or seen in the areas she cherished, particularly the Library and the Yellow Drawing Room. Unlike more unsettling phantoms, Lady Baillie's presence is generally perceived as warm, gentle, and almost protective, as if she continues to oversee her beloved home and ensure everything is maintained to her standards. Some night watchmen and guides have reported fleeting glimpses of her or the faint scent of her favorite perfume.
