Abstract:		 Between the 7th of July 2012 and the 20th May 2013 two test pits and a construction shaft were monitored by Compass Archaeology during groundworks associated with a new sewer connection towards the northeastern end of St Mary Axe, City of London. The works were located over the line of the former City ditch, which was backfilled by the 16th century. The trial pits and construction shaft all showed signs of heavy disturbance in recent times either through the insertion of modern services or through later post-medieval development of the area in the form of brick-built structures. Made ground was visible for almost the entire depth of the final shaft, (0.45-4.5m below ground level), with only a metre of earlier, truncated, silt deposits observed towards the base of the pit, (4.5-5.5m below ground level). These deposits directly overlay natural ground, observed from c5.5m-7.5m below ground level - the interface between the two correlating to c6.75mOD. The dark-grey clay-silt deposit observed towards the base of pit 3 is believed to be a later medieval backfill / silting episode within the base of the City ditch.
