Wessex Archaeology was commissioned by Greencore Construction Ltd (the Client) to undertake an archaeological strip, map and record excavation on land at 49 Preston Crowmarsh, Oxfordshire, OX10 6SL. The fieldwork was undertaken on 25th and 26th March 2015. The small area (approximately 160m²) was excavated prior to the erection of a detached dwelling with new vehicular access and associated parking and amenity space provision, and revealed a small number of archaeological features. Two large intercutting pits were recorded, although their function was not clear. Pottery recovered indicates that an earlier medieval pit was later truncated by a post-medieval feature. A third, much smaller, pit was also excavated and contained Anglo-Saxon, medieval and post-medieval pottery. No further archaeological works are recommended on the site.
