'The hall was probably first built around 1260, by Adam de Singleton. Most of the original moat still survives. ... Visitors to the hall are shown a window where it was claimed a light was shone to show it was safe to attend Mass in the Hall at a time of persecution. A number of secret 'Priests' hiding holes' have been discovered. There have been many reports of hauntings, noises and cries. (Ghosts, Traditions, & Legends of Lancashire. Sigma Press.
