6. Ballygally Castle, Coast Road, Ballygally
While now a popular hotel, Ballygally Castle has a long history of ghostly encounters, including one of its most famous stories regarding the ghost of Lady Isabella Shaw, who was locked into a small room by her husband after she had given birth to a daughter. The story goes that while starving and tormented by her baby’s cries, Isabella tried to escape through a window but fell to her death on the rocks below. Her spirit is said to roam the castle, often making her presence known through cold spots and unexplained events, with this tale resulting in the castle being featured in Jeff Belanger’s book ‘World’s Most Haunted Places.’ Photo: Hastings Group / Christopher Heaney
