Abstract:		 Between the 20th and 27th January 2021 Compass Archaeology undertook an archaeological evaluation at 8 Abbey Gardens, Chertsey, in the county of Surrey. The evaluation was commissioned to accompany an application for Scheduled Monument Consent to extend the present property. The site was subject to Scheduled Monument Consent due to its location within the wider site of Chertsey Abbey a medieval monastic site. The evaluation comprised the hand excavation of four trial trenches within the footprint of the proposed development. The upper layers of all three trenches had much the same sequence, with c.300-500mm of topsoil and made ground overlying a former land surface, which dates to the mid-1950s development of the site. Below this was a basic alluvial profile, rather than a properly worked soil, which presumably reflects the low-lying and likely periodical flooded nature of this area. In Trench 1 a thick alluvial deposit sealed an earlier water channel or ditch (base at 11.34mOD), which may be associated with the feature on roughly the same NW-SE alignment recorded during an evaluation at No. 6 Abbey Gardens (AYG18). Trench 2 was shallower, with the alluvial sequence coming down onto a natural deposit. Trench 3 revealed a further deep cut feature also aligned approximately NW-SE, although due to its location on the south-west side of the trench, its nature and extent were not fully established. Natural geology was observed in all three trenches. In Trench 1 a sterile light yellow-brown sandy silt with fine orange mottles was observed from 11.68mOD at the base of the sondage into the north-east corner. In Trench 2 the natural was an orange-brown clayey silt present from 12.39mOD. The natural deposit in Trench 3 was a sterile yellow-brown silty clay with occasional pebbles, which was observed from 11.82mOD. Trench 1 contained relatively clean alluvial deposits which sealed an earlier ditch or channel. Its fill comprised an alluvial deposit with occasional CBM and chalk flecks as well as sherds of late 13th century pottery. The ditch or channel feature may be associated with the feature roughly on the same NW-SE alignment recorded during an archaeological evaluation at 6 Abbey Gardens (AYG18; Compass Archaeology 2018). This feature previously observed was interpreted as a possible feeder channel supplying the throughflow of water into a pond between the western and eastern branches of the 'Black Ditch'. This feature may have originated as a monastic enterprise which, subsequently to the remodelling or dissolution of the monastery, lost its function and silted up. Additionally, the top of the alluvial sequence in trench 1 sloped down towards the southern end of the trench, towards the possible fishpond shown on old surveys up to the 1950s. Evidence of structures in the form of CBM was recovered from all trenches. Several pieces of worked and unworked stone and an iron-type material were recovered from trenches 1 and 3, which may have derived from the demolition of the Abbey and its associated buildings and wre possibly brought to the site for reuse in later construction.
