Description

Archaeological monitoring and recording was carried out at Priory Street Car Park during the redevelopment and enhancement of the car park in 2016; only the groundworks for the redevelopment and enhancement of the eastern half of the site, were carried out before CAT was appointed to carry out the archaeological monitoring and recording.<1> Groundworks included the construction of a french drain, c.150m long x 1.5m wide and 1m deep, trenches for streetlight cables, c.0.6m wide x 0.60m deep, with the holes for the lamp posts measuring c.0.8m wide by 1.20m deep. Tree pits, c.0.3-0.4m deep, were also monitored across the carpark. Groundworks revealed modern layers (L1, L2 and L4) to a depth of 0.5m below current ground level (bcgl). Sealed beneath were patches of a post medieval/modern silty loam (L3) between 0.5-1.2m bcgl probably associated with housing on the site since the 18th century. Between and sealed by L3 were pockets of 'dark earth' (L5) also identified at depths of between 0.5-1.2m bcgl. This layer of 'dark earth' was interpreted as the very top fill of the Roman town ditch or a layer of post-Roman topsoil accumulated over the ditch. Consequently, the groundworks showed that significant archaeological horizons have survived in places at a minimum depth of 0.5m bcgl.
