Excavations on the outskirts of Shrivenham have revealed multiple phases of ditched boundaries and enclosures. A substantial east-west aligned ditch, which was up to 9m wide, was also present. This major landscape boundary terminated at the west, within the site area. An egg-shaped enclosure, located immediately to the north of the substantial ditch, was likely to be contemporary with it. Other features included a clay-lined stone-built well, numerous quarry pits, circular vertical sided flat based pits, small clay-lined pits and dispersed postholes. There was no evidence for on-site occupation or settlement. A fairly substantial pottery assemblage was dominated by Iron Age wares, with some Roman. Other recovered artefacts included an iron sword (recovered from the fill of the substantial ditch), loom-weights, animal bone, a piece of Roman box-flue tile (recovered from the latest re-cut of the substantial ditch) and a small amount of struck flint. The site appears to be situated at the western edge of an extensive area of fairly intensive Iron Age to Roman industrial activity with evidence for multiple phases of ditched and presumably formalised demarcations of space.
