This work presents a history of Dorchester-on-Thames, Oxfordshire, in an overlapping double vision. One image presents the more traditionally understood place that Dorchester holds as the 'oppidum' that grew to be a town and retained that urban identity in the face of the crumbling fifth century, while the alternate hypothesis challenges the notion of 'urban' community, suggesting that stability of geographical presence and perseverance of spatial identity are more considerable factors in the longevity of Dorchester's significance.
