“At the end of the investigation one of our trenches came up with a substantial stone wall while the one behind came up with a great mass of building rubble and medieval pottery.
“We put in a larger trench and came up trumps. We got a substantial medieval wall in the south west corner of the building.”
It is thought the wall belonged to the chapel of a priory founded by the Abbey of Mont St Michel in Normandy around AD1150.
