An excavation was carried out in 2003 when the Air Balloon public house was being redeveloped for housing. Rubbish pits, postholes and a possible ditch were found, with medieval pottery. The pottery dates to the 11th to 14th centuries, showing that people were living in this part of Ock Street, close to the Ock Bridge, at that time.
