Retaining Wall to Churchyard from Deanery Gate to Ford opposite Bishops Palace, including Front Wall

Rubble stone retaining wall, free-standing at S end where there are a pair of big squat square stone piers with pyramid caps to Deanery Gate carriage entry. C20 wooden gates, and small stone kissing gate to N. From gate, some seven metres length, then retaining wall of some 22m length with two blocked loops at S end, similar to those in N wall of C14 St Mary's College and indicating the site of the undercroft described by Archdeacon Yardley in early C18 as 'one large vault of equal length, where materials are deposited for ye use and repairs of ye church".

Yardley states that the school, previously in the W cloister, was moved here to what was a 'storehouse, or workhouse for ye use of ye church', and presumably a schoolroom was built above, that survived until 1791 when John Nash converted it into a much criticised chapter house which was demolished 1829. It is not known how much survives of the undercroft.
