Oxford Archaeology was commissioned by PCA Architects to undertake a strip, map and sample excavation at the site of a proposed dwelling at Moreton Lane, Northmoor, Oxfordshire. The site lay within a Scheduled Monument comprising an extensive area of cropmarks thought to be principally of Iron Age and Roman date. Watching briefs had previously been undertaken at the site in 1995 and 2007 in advance of construction of agricultural buildings. The excavation uncovered ditches of mid to late Roman date that defined the boundaries of rectilinear enclosures that abutted a trackway to the west, part of which had been uncovered by the 2007 watching brief. There was no definite evidence regarding the function of the enclosures, but it is evident from the artefactual assemblage that domestic occupation lay somewhere nearby, although no structural remains were uncovered.
