Littlemore Priory was founded in 1110 and shut down in 1525, and during the excavation, nearly 100 skeletons of men, women and children were uncovered, according to the Huffington Post.
The remains, however, were arranged in a very peculiar, unusual fashion, not typical of a regular burial.
One woman was buried in a "face-down position" (a practice reserved for witches), and researchers believe she may have been one of the infamous "sinner nuns" who forced the nunnery to shut down.
Other unusual burials included a stillborn baby in a casket, skeletons thought to have had leprosy and one that looked as if it had trauma to the skull.
"Burials within the church are likely to represent wealthy or eminent individuals, nuns and prioresses," lead archaeologist Paul Murray said. "Those buried outside most likely represent the laity and a general desire to be buried as close to the religious heart of the church as possible."
The majority of the burials were females, at 35, with males accounting for 28. The researchers said it was impossible to determine the gender of the remaining 29 skeletons.
"It's unusual for someone so young to be buried within the church," Murray said, regarding the infant.
"And sometimes women found in prone positions are considered to be witches. Another possibility is that she sinned during her life and to atone for her sins she requested to be buried face down," he added.
The priory had a controversial history. In her book "Medieval English Nunneries," Eileen Power described it as "in such grave disorder that it might justly be described as one of the worst nunneries of which records survived."
"This was largely due to a particularly bad prioress, Katherine Wells."
Wells was described as an immoral, sex-crazed nun who had an affair with a priest, with whom she bore an illegitimate daughter, who then forced the nuns of the priory to lie on her behalf regarding the affair, Huff Post reported.
She was also accused of stealing from the nunnery to provide a dowry for her daughter, as well as "playing and romping" with the young boys in the cloister, according to the Daily Mail.
In 1524, Thomas Wolsey, the Lord Chancellor, recommended that the priory be dissolved.
No solid plans for the medieval nunnery have been made yet, though once excavation is done, it may become the restaurant portion of a new hotel being built at the medieval site.
