In June 2020, Oxford Archaeology (OA) was commissioned by RPS Group to undertake a field evaluation on land at Maylands Avenue, Hemel Hempstead. Seventeen trial trenches were excavated within and around the footprint of an old industrial factory, representing a 4% sample of the proposed development area. The site is located near the Roman temple-mausoleum complex at Wood Lane End and had the potential to contain important archaeological remains. The evaluation revealed no significant archaeological remains and the stratigraphic sequence suggests that the site has been heavily truncated and disturbed by the previous land-use. Areas of undisturbed ground were extensively investigated to the east of the site, but again no archaeological remains were identified. The presence of demolition spoil, modern building remains and services restricted the layout of the trenching and necessitated the relocation of several trenches from the central area to the northern part of the site. A small number of finds of late post-medieval and modern date were recovered during the investigation from truncated furrows. Based on the results of the trenching, the site has been significantly truncated by modern disturbance and is considered to have low potential for the survival of archaeological remains.
