Originally a monastery under the Cluniac order, Monk Bretton Priory is located in the village of Lundwood, in the borough of Barnsley, England. It was founded in 1154 as the Priory of St. Mary Magdelene of Lund by Adam Fitswane, sited on the Lund, from Old Norse. In the course of time the priory took the name of the nearby village of Bretton to be commonly known as Monk Bretton Priory. The monastery closed on 30 November 1538 during the dissolution, and the site passed into the ownership of the Blithman family. In 1580 the land was again sold to George Talbot, 6th Earl of Shrewsbury who gave the estate to his fourth son Henry on his marriage to Elizabeth Rayner. The site is a Scheduled Ancient Monument and now in the care of English Heritage.
Excavations concentrating on the church and cloister took place on the site in the 1920s which were published by the Yorkshire Archaeological Society and other largely unrecorded digging by the Ministry of Works took place during the 1950s. More recently the site has been the focus of a survey and excavation project run by the University of Sheffield.
