The car parking area south of the Musket Club lies over an archaeological ‘cropmark site’ recorded in the 1070s – a sub-rectangular enclosure of suspected Iron Age date (EHCR 11839). A watching brief was carried out on various minor service works connected with the redevelopment of the site. In addition, an area 14 x 20m which coincided with the northern arm of the enclosure was cleaned by hand, and three sections were cut across the ditch. The ditch was recorded in contractors’ trenches at a further three points on its circuit. Modern service-trenches had caused much disturbance to the ditch, but a small quantity of pottery indicated a Middle Iron Age or later date for the enclosure. <1> This work follows two trial trenches excavated in 2002, in the centre and across the north-western angle of the enclosure ditch (CAT Report 207). The north-west angle of the enclosure ditch was located, but heavy disturbance from modern mains and other works had severely truncated the Iron Age remains. <2>
