Six evaluation trial trenches (87m in total, each 1.6m wide) were excavated by Colchester Archaeological Trust at St Helena's School in advance of plans to extend the school car-park in the south-east part of the site. Four of the trenches were dug through a grassed area and two were dug through an asphalt surface; the site was grassed playing fields and waste ground at the time of the evaluation. Archaeological features were defined at c.0.70m (min.) below the ground surface.<1> A total of 18 features were recorded, concentrated in (but not exclusively) in Trenches 1 and 2, the two westernmost trenches that lie within the temple precinct: 10 Roman (seven pits, a partially robbed wall foundation, one ditch and one metalled surface); one mid/late Bronze Age pit; one post-Medieval ditch; six undated features (four pits and two ditches); and one natural feature. The wall foundation, defined at the east end of T1, appears to have been part of the precinct wall for the late 1st century Roman temple (Temple 2). A large quantity of Roman finds were also recorded including two coins which belong to the post conquest pre-Boudican occupation of Sheepen, a brooch fragment and briquetage which may also date to before AD 60/1, and a number of potsherds dating primarily from the 1st to the early 2nd century.
