The watching brief comprised the recording of open groundworks and recovery of exposed/disturbed artefactual material, followed by the observation by a competent archaeologist of all further intrusive groundworks associated with the proposed development in the area, and further metal-detector scanning of the open excavations. These works comprised the machine excavation of foundation and service trenches. In September 2019, Cotswold Archaeology carried out an archaeological watching brief during groundworks associated with residential development at Project Aquarius Bamfileld, Hengrove, Bristol. A coin hoard, consisting of pottery vessel container, copper-alloy scale pan lid, and 309 bronze and silvered-bronze coins, was recovered following emergency attendance during development groundworks. The recovered coin assemblage dates exclusively to the middle of the 4th century AD and included a significant number of coins struck by the usurpers Magnentius and Decentius, who ruled the western provinces of the Roman Empire between 350 and 353.
