SNN113259 - Images and GIS Data from an Archaeological Evaluation at Junction 15, M1, Collingtree, Northamptonshire March to April 2018

This collection comprises images and GIS data from an archaeological evaluation at Land off Junction 15, M1, Collingtree, Northamptonshire. This fieldwork was undertaken by Cotswold Archaeology between March and April 2018 and involved the excavation of 58 trenches. The evaluation identified archaeological remains concentrated within five main areas of the site with a low density of archaeological remains identified within two further trenches. Although a number of these features remain undated, the majority can be attributed to one of four broad periods; the Middle Iron Age, Late Iron Age/ Early Romano British (early to late 1st century), Romano-British (2nd to 4th Century) and medieval. The results of the evaluation correlated well with the preceding geophysical survey, which identified a number of anomalies representing potential archaeological features, comprising circular, linear and discrete anomalies indicative of prehistoric enclosures, trackways, pits, agricultural ditches, furrows and boundary features. The pattern of enclosures predicted by the geophysical survey was largely confirmed by the evaluation. The earliest evidence of prehistoric activity identified on site comprised an undated ditch overlain by a charcoal rich deposit containing waterlogged wood, radiocarbon dated to the Middle Bronze Age. The artefactual evidence recovered during the evaluation suggests that permanent settlement within the central area of the site began during the Middle Iron Age, with evidence for more extensive settlement in the form of enclosures, trackways and other settlement features predominantly dating to the 1st century AD. An area of 2nd to 4th-century settlement was identified within the north-western part of the site. Features associated with medieval and post-medieval land use were also recorded.
