Evaluation by T Smith of Bristol & Region Archaeological Services recovered evidence for flint-working consisting of microdebitage, including complete and broken flakes and one small exhausted pyramid core of probable Mesolithic date. Recovery patterns suggested the assemblage was evenly distributed within the gravel deposits. No knapping concentrations were evident and it is likely that any former ground surfaces were removed during later landscaping, probably in advance of the construction of the Brethren’s Hall.
