The traces of medieval activity on the site were apparently truncated by later disturbance, so that all that normally remained were pits or gullies, datable by the few pieces of pottery they contained.
Pit 244, 0.90m square and cut by Rainbird's trench, contained six large burnt stones (237) beneath a loose, black, ashy fill (238). There were lenses of sand and silt (245) to the north of 244, apparently cut into the Roman road surface, and these overlay a sandy silt (249) containing charcoal, gravel, mortar, large stones, and medieval pottery.
Various other pits produced medieval pottery, such as a shallow cut (219) in the south-western quadrant.
There is a noticeable absence of any indication of the presence of the early ecclesiastical community at Chester-le-Street, but this could be almost wholly due to the removal of relevant contexts during subsequent levelling activities, so the Church Chare excavations can neither prove nor disprove re-use of the Roman fort.
A circular, stone-lined pit (252) on the western side of the site was associated with a rubble spread (055). It is likely that the site was levelled, removing much of the Roman material on this western portion, in preparation for the laying of this surface. The pit was 1.26m in diameter and 0.94m deep, and lined with nine stone slabs (at least one of which had a nail hole, suggesting that it was re-used roofing material) around the sides, held in place by wooden pegs. It also had a paved floor. A crude flight of eight stone steps led down to the pit from the north. The fill of the pit included 16th and 17th century, as well as Roman, pottery.
Mortared east-west (139) and north-south (114) walls represent the remains of the first of two modern structures on the site. 139 rested almost directly on the surface of the disused via sagularis, presumably as a result of levelling. This structure was associated with a pebbly floor surface (112) and two lines of kerbstones (305, 317) of an east- west cobbled lane, largely removed during initial machine stripping. The kerbstones rested on an ashy spread (321) and included within their confines a mixture of sandstone fragments, mortar, and gravel.
A later structure, readily identifiable as the terrace of cottages demolished within living memory, was set at an angle (aligned north-north-west to south-south-east) to the previous building. The front wall (009, 306?) facing Church Chare itself was mortared and associated with a cobbled surface (011), whilst the back wall (027) met the rear wall of the old school yard (025, 035), the continued line of which now forms the southern boundary of the Salvation Army property. The remains of a dog (037) were found buried in the garden of one cottage, whilst the services to these cottages (007-008, 015, 026, 045, 047-050, 053) caused much of the modern disturbance to the area of the officer's quarters, particularly in the western half and in the centre of the north wall.
