Churchill Hospital, Oxford, Clinical Biomanufacturing Facility

Two evaluation trenches were excavated in October 2015 at the Churchill Hospital,
Oxford on the site of the proposed Clinical Biomanufacturing Facility, immediately
west of the location of Roman pottery kilns excavated in the early 1970s. The
sequence in both trenches comprised the natural sand subsoil overlain by a brown
sand deposit of uncertain date. This was cut in both trenches by a large pit
containing modern building material amongst other rubbish. These two intrusions
were probably parts of a single feature, the limits of which to north, south and east
are unknown but was at least 12m in extent north-south by at least 7m east-west. In
Trench 2 the base of this feature was c 1.2m below modern ground level and any
earlier deposits in this area would have been completely destroyed. The fill of the
feature(s) was sealed by a levelling layer of similar material beneath the current
carpark surface. No features or deposits of archaeological interest were present
and only a single sherd of Roman pottery was recovered
