An archaeological evaluation consisting of two trial trenches was undertaken on behalf of Professor Peter Fidler in an area close by Roman and Anglo-Saxon settlement remains, prior to the construction of an extension and new garage block. The evaluation revealed three Roman ditches and one undated gully sealed under a considerable depth of plough soils. The foundation trenches of the proposed development will likely impact on the archaeology but the floor formation levels, services and drainage are unlikely to penetrate through the exceptionally deep plough zone. An archaeological watching brief was carried out during the excavation of foundation trenches for a new extension and double garage in ana area where evaluation had determined Roman deposits survived on behalf of Professor Peter Fidler. Evaluation: The evaluation revealed three Roman ditches and one undated gully sealed under a considerable depth of plough soils. The foundation trenches of the proposed development will likely impact on the archaeology but the floor formation levels, services and drainage are unlikely to penetrate through the exceptionally deep plough zone. Watching Brief An early phase of activity is evident in the form of handmade pottery of probable middle Iron Age date. The activity continued into the 1st century AD judging by the presence of Aylesford - Swarling tradition fabrics and together the evidence suggests the location of a farmstead. This is one of a number of complexes along the Avon Valley at Tiddington which seem to have coalesced into a village which thrived throughout the Roman period.
