This collection comprises digital photographs and reports from the watching brief carried out by Pre-Construct Archaeology Ltd at 61-64 High street, Southampton from March to July 2021. Groundwork to form foundations for extension to existing building were monitored. Very limited access was possible but archaeological deposits were visible in section and plan between 1.2m and 1.6m below existing ground level, in places heavily disturbed. The archaeological features included deposits and cut features, but were not datable.
