Six evaluation trenches were excavated at the staff and student car-parks at Colchester Institute in April 2006, in advance of the construction of new college buildings and two multi-storey car-parks. The evaluation produced evidence on the site from the Late Iron Age and Roman periods. Fifteen cut features, principally quarry pits and ditches dating from the Late Iron Age to the 1st century and the later Roman period, were identified. A spread of Roman pottery and building material indicate the site of a Roman building nearby, although no structural features were present. Some of the features were within the date range of the pre-conquest phase of the Sheepen site (c.AD 5-43) and could be considered to be part of the pre-Roman site. Although no waterlogged features were identified, the depth of deposits and the water table in the student car-park trench suggest that waterlogged remains may be preserved. <1> A second phase of the evaluation was carried out in August 2006. <2>
