A trial trenched evaluation was undertaken at the Central Clinic, on the north side of the High Street (between Castle Park and Greyfriars Commuinty College), in May 2006, in advance of redevelopment. In addition, three boreholes were monitored. A N-S aligned Roman street was defined in Trench 2. Evidence for a Roman structure east of the street took the form of two parallel robbed- out walls (F3, F4). In Trench 5, a series of modern cuts F17 (1963 excavation trench?), pit F21, service trench F20 and large cut F31 left significant archaeological deposits in isolated blocks or ‘islands’. These were tessellated floor F16 and gravel patches F18 and F19. The tessellated floor ran up to the south edge of the trench, and presumably survives to the south of T2. The gravel patch F19 is on the line of the Roman street exposed on T2, and is undoubtedly part of it, whereas F18 is too far east, and is more likely to have been part of a gravel yard or path. The trial trenched evaluation followed a desk-based assessment compiled by Colchester Archaeological Trust. <2> It was followed by an archaeological watching brief during redevelopment. <3>
