An area about 30m by 11m, on the Marygate street frontage, was excavated by archaeologists in 1999. A number of pits were found across the site and at least 45 were investigated. The largest pit measured 5m in diameter by 1.6m deep. Most of the pits seem to be of medieval date and were probably used for rubbish disposal. Pottery from the pits included much 13th and 14th century wares. The preservation of organic material was extremely good across the site and included wooden and leather artefacts, plant matter and bones from fish, birds and marine mammals. Evidence of medieval buildings was also uncovered, including three post pits from the back wall of a timber building and a very substantial oak post found in a post hole at the rear may suggest a second structure of high status. Other features included medieval property boundaries, a stone-lined pit and a stone-lined well - filled and capped in the medieval period.

A large scale excavation was carried out on the street frontage in October and November 1999. Details as above. (2)
