The haunting
The best-known haunting concerns Thomas de Gretham, a 14th-century abbot of Thornton. According to the legend, Gretham was accused of witchcraft and black magic and was supposedly walled up alive in a chamber beneath the abbey. His ghost is then said to have remained at Thornton, with reports of a spectral monk appearing around the ruins and particularly around the imposing gatehouse. There is an intriguing historical element behind the story. English Heritage records that, according to antiquarian accounts, the remains of a canon who had apparently been immured were discovered at Thornton around 1722. The skeleton was reportedly found sitting at a table with a book and candlestick. Later writers associated the remains with the 14th-century abbot Walter Multon, while the ghost tradition identifies the figure as Thomas de Gretham.
Reported / claimed activity
◆ THE GHOSTLY MONK — A male apparition associated with the former abbey. ◆ THOMAS DE GRETHAM — The ghost is traditionally identified as the 14th-century abbot accused of witchcraft. ◆ THE GATEHOUSE APPARITION — Reports describe the figure appearing around or looking out from the enormous medieval gatehouse. ◆ THE WANDERING ABBOT — His spirit is said to wander through the ruins and surrounding grounds. ◆ THE BRICKED-UP CHAMBER — Folklore claims the abbot was sealed inside the abbey and left to die. ◆ THE SKELETON AT THE TABLE — Historical accounts describe human remains reportedly discovered with a table, book and candlestick. THE STORY OF THE GHOST MONK The legend centres on Thomas de Gretham, who was supposedly involved in an illicit relationship with Heloise, the daughter of Sir William Wellen. According to the later ghost story, Heloise's father discovered the relationship and accused the abbot of immoral behaviour and witchcraft. Gretham was supposedly convicted and sentenced to an exceptionally cruel punishment — being sealed alive inside the abbey. The story says that centuries later, during work at the abbey, labourers discovered a bricked-up chamber containing a skeleton sitting at a table. A book and writing materials were supposedly beside the remains. The discovery became connected with the story of the imprisoned abbot, and reports subsequently developed that his spirit could still be seen around Thornton Abbey.

Historical background
Thornton Abbey began as an Augustinian priory in 1139, founded by William le Gros, Count of Aumale and Lord of Holderness. It became an abbey in 1148 and grew into one of the wealthiest Augustinian religious houses in Britain. Its location near the Humber estuary helped it become an important economic centre, with extensive lands, livestock and trade. The surviving gatehouse, constructed between 1377 and 1382, is particularly impressive and is the largest surviving monastic gatehouse in Britain. The abbey was suppressed in 1539 during Henry VIII's Dissolution of the Monasteries, although Thornton was subsequently refounded as a secular college before finally being closed in 1547. Thornton also has a particularly grim archaeological history. In 2013, archaeologists discovered a mass grave containing 48 skeletons, including 27 children. Scientific analysis established that those buried there were victims of the Black Death, which reached this part of Lincolnshire in 1348–49. A medieval hospital associated with the abbey was also identified nearby.
