An archaeological evaluation was carried out Area S1, ahead of the development of the Garrison Alienated Land (GAL), Colchester Garrison. <1> <2> Area S1 comprised a 10.27ha area located on the north side of Berechurch Hall Road, and east of the perimeter fence of the Roman Barracks. This was an area of former arable land which was 'set aside' at the time of the investigation. The dyke defining the eastern side of Camulodunum, Berechurch Dyke, runs down the western side of Area S1. At stage 1b, the priority was to establish the expected alignment of the Berechurch Dyke through S1, so that an undeveloped green 'corridor' could be left in order to preserve its line and setting within the GAL scheme. Therefore, the primary objective for Area S1 was to identify the location and extent of Berechurch Dyke to ensure that it was avoided by both built development and also by a new service trench along the east side of Roman Barracks. Three evaluation trenches, totalling 150m in length were excavated. These trenches located the defensive ditch of the dyke and a previously unknown second ditch. A further two trenches, totalling 9m in length, were placed over this second ditch to determine its nature. The remains of Berechurch Dyke, consisting of the ditch and the surviving rampart, were located within the evaluation trenches. The Dyke ran north-north-east/ south-south-west through the western edge Area S1 with its ditch located on the eastern side of the rampart. T1 and T2 showed that the ditch survived to a width of 6.8m and a depth of over 1.4m. T3 showed that it had been cut away in the southern part of the site by another large post-medieval ditch. The post-medieval ditch survived to a width of at least 3.7m and a depth of at least 1.00m and therefore represents a substantial boundary; 20th century material in its backfill indicates that it had not been filled in (or allowed to fully silt up) until recently. The stage 1b evaluation followed an earlier (stage 1a) evaluation across Area S in 2002 (8 trial trenches in this 23.6 hectare area, Trenches S1-S8). <3>
