A magnetometry and earth resistance survey by R and S Ainslie of Abingdon Archaeological Geophysics within the boundary of the Scheduled Monument revealed three anomalies of possible archaeological origin. A subsequent test pit evaluation by W Weller of SCAU revealed a segment of a possible early medieval ditch towards the north of the site and confirmed that some areas to the south of the site had been truncated by recent quarrying.

Evaluation by W Weller of SCAU revealed a posthole containing a small assemblage of pottery of Late Bronze Age or Early Iron Age date. A larger collection of struck flint recovered from the posthole and within the overburden was of similar later Bronze Age date.
An archaeological strip, map and sample excavation by W Weller of SCAU revealed archaeological deposits of multiple periods with Late Bronze Age and Roman features the most dominant. A series of three excavations was conducted in the same area during the 1970s and this phase of work represented a chance to further enhance the understanding of settlement activity in the area.
Watching brief by W Weller of SCAU, adjacent to the recently recorded site of a probable Middle Iron Age through to the early Saxon farmstead (SyAC 99, 229), revealed no further archaeological finds or features.
Watching brief by M Saywood of SCAU did not reveal any finds or features of archaeological interest.
Archaeological monitoring by J Payne of SCAU during limited pipeline repair works within the Scheduled Monument area of the Roman road Stane Street. The previously recorded dimensions and make-up of the Roman road (SyAC 75, 289) were confirmed while the presence of a possible levelling deposit associated with the initial construction of the road, and not previously recorded, was also revealed.
Evaluation by T Collie of SCAU across former tennis courts revealed ground levelling in the form of made-ground, and a short section of a probable 19th century brick foundation, but no finds or features of archaeological interest.
Evaluation by W Weller of SCAU revealed deep levels of made-ground comprising a high percentage of industrial slag and ash as well as sand, brick, stone and 20th century household waste. The results show that deep excavations had been conducted across most of the site prior to the construction of the football ground in the early 1950s. There was no indication of the projected route of Stane Street, sometimes postulated to cross the site, although the depth of disturbance would probably have removed any evidence if it had been present.
Watching brief by W Weller of SCAU during construction of a temporary school building and hard play area revealed no finds or features of archaeological interest, although the archaeological horizon was encountered only in the building foundation excavations.
Third and fourth seasons of a community excavation by SyAS and SCAU, under the direction of R Poulton, of the Scheduled moated site. The 2011 work took place in three locations. Within the first trench, the remains of part of the gatehouse and associated structures were uncovered next to the present (and ancient) site entrance. These buildings had stone foundations and would mostly have been of timber-framed construction. The addition of brick hearths shows that they were updated over time. A robber trench at the eastern edge of the trench had clearly removed a substantial wall.
