He said: “The bones are really perfectly preserved apart from where early 20th Century foundations have chopped through them so in places you’ll only get half a body.
“Even when the friary was in use they sometimes chopped through the burials – so it’s not just in the modern period that the skeletons have been disturbed.”
The Augustinian friary was founded in 1290 but fell victim to the dissolution of the monasteries in 1538 under Henry VIII.
“They come in, they set up their friary and mark off an area as a cemetery and they start burying people in nice neat rows,” Mr Cessford said.
