Large two storey buildings, one of which covered a cellar, were excavated during a rescue excavation in . This structure measured 8m by 4m, with a depth of over 2m, was notable for a pair of well-preserved windows, protected on the outside of the cellar by two small retaining walls, forming a light well. Although the proposed new buildings on the site would have destroyed at least one of these windows, plans were altered to preserve them both. Finally in the 1650's the buildinsg were pulled down and the cellar filled in.
