Post-excavation assessment of a series of evaluations, excavations and a watching brief carried out by the Colchester Archaeological Trust in association with RPS Planning Transport and Environment and on behalf of Taylor Woodrow, in 2004 - 2005, on areas C1, C2, E, J1, O, Q and S1 ahead of the development of the Alienated Land at Colchester Garrison. The report also includes the Time Team trenches and the Alienated Land watching brief. Area C1 included the remains of a short section of a large Roman circus found across the Alienated Land development area. Other archaeological activity recorded from the site included a series of Late Neolithic features, three boundary ditches forming part of the Late Iron Age/early Roman field system, a Roman road, a post medieval ditch and a number of modern/military features. Area C2 was dominated by a large late Roman cemetery and intercepted a short section of the remains of the large Roman circus found across the Alienated Land development area. Other archaeological activity recorded from the site included the remains of a single Late Neolithic pit, a Roman drove way/track, a number of post-medieval pits and some modern/military features. Area E included a series of field boundary ditches and a Roman enclosure containing a small villa/farmstead. Other archaeological activity recorded from the site included the remains of a post-medieval ditch that may be associated with siege works constructed during the English Civil War. Area J1’s northern area was dominated by a large Roman cemetery. The eastern area dominated by the remains of the large Roman circus found across the Alienated Land development area, whilst a wide Roman road and smaller drove way were located in the southern area where a much smaller burial plot were also encountered. Other evidence included a small number of Late Bronze Age features, a series of post-medieval field boundary ditches and road, and a number of modern/military features. Area O contained a single Roman field boundary ditch. Area Q was dominated by Late Iron Age/Roman field boundary ditches. Other evidence recorded from the site included a prehistoric 4-post structure, three Roman graves, three possible stake holes and two hearths. The archaeological investigation of Area S1 successfully located the ditch and rampart of Berechurch Dyke. A post medieval ditch was also recorded during the investigation. The Time Team trenches successfully located part of the walls of the Roman circus, the starting gates and the spina. The trenches dug during the watching brief for a storm water drain exposed three prehistoric pits, three sections of the Roman circus (which included two sections over the outer and inner cavea walls, an entrance and part of the spina comprising a probably monument base), a single Roman burial, several medieval robber trenches and a number of post-medieval features. <1> See CAT Report 412 for the analytical report. <2>
