A trial-trenched evaluation (five trenches, 53.0m in total length x 1.80m wide) was undertaken at Bridge House, Hythe Quay, Colchester, in 2018 during the pre-determination stage of planning, to inform a planning application for the proposed construction of new residential dwellings.<1> Three medieval pits were excavated in trench T1 with a medieval pit and linear in trench T4, dating from the late 11th to the 13th/14th century. In T4, there was also a medieval (late 12th to 14th century) wall foundation of medium to large compacted stones (F7). Looser patches of compacted medium stones and chalk may represent a second later wall foundation (15th to 17th century) but could also be the remains of either a plinth or surface (F8, F16 and F17). These were recorded beneath L1 (0.25-0.45m thick) and sealed/cut by postmedieval/modern disturbance (L15, L16, F11 and F18), a post-medieval/modern pit (F2) and the disturbed remains of a post-medieval brick foundation with sand base (F10). There were no significant archaeological remains in two trenches (T2-T3). The evaluation produced finds of Roman, medieval and post-medieval date, of which the majority consists of medieval pottery which can be dated to the period c.12th to 14th century. Finds of Roman date consist of a single sherd from a Dressel 20 amphora and a few pieces of Roman brick or flat tile. The finds that can be closely-dated to the medieval period consist of pottery sherds, totalling 87 sherds with a combined weight of c.1.1kg. These include finewares, with several sherds from glazed jugs that can be identified as Hedingham ware, although the majority consists of coarsewares, almost certainly of local origin and mostly representing cooking pots.
