The Lady chapel was preserved by use as a roofed farm building during the 18th century, and was re-thatched as a place of worship during the 20th century. Excavations during the 1980s established the position of the lost south wall and turret of the brick entrance-gate structure, and explored the interior of the reredorter building. In a separate investigation, the interior of the presumed abbey Guest Hall was excavated. Two long upstanding medieval walls had survived: they are incorporated into a new structure for the use of Pro Corda.
