A trial-trench at St Helena School revealed thirteen archaeological features. Three features were dated either Late Iron Age or Roman - two pits/post-holes, and a gravel surface. The other ten features included two post-medieval ditches, and eight undated pits or post-holes.

During the excavation of the north lift shaft pit a small quantity of human bone was recovered near the base of the excavation, during a watching brief and excavation in advance of redevelopment at 38-42 Crouch Street, Colchester, on the site of the (later) medieval Crouched Friars friary (Grave 53, find number 127). As no burials were located during the watching brief on the central or west areas of the site and all of the medieval burials were located on the west side of the site it appears likely that this bone represents a disturbed Roman inhumation. A small number of Roman inhumation burials were located just to the west of the current site during the 1988 excavation (CAR 9, 247-48) and a larger number were excavated to the south of the current site during excavations in advance of the construction of the inner relief road in 1971 (CAR 9, 236-41).

11th century Abbey, founded in 1096 by Eudo Dapifer and dissolved 1538. The most significant surviving element is the N. gatehouse (see MCC415), probably C15 in date, with parts of the original C12 precinct wall surviving along Mersea Road, Napier Road and Flagstaff Road (see MCC441). The site of the Abbey Church is recorded by archaeological investigations (see MCC419, MCC3067).

Castle comprised an inner bailey around a keep, and an outer bailey between the inner bailey and the N wall of the town.

17th century building, (CAT Building 151), Long Wyre Street, recorded during excavations in 1979.

Undated inhumation from Trench A10 (Area A) defined during evaluation in 2002 at Colchester Garrison Alienated Land Area A1 (former Meeanee & Hyderabad Barracks), Mersea Road, Colchester.

Cropmarks of probable former field boundaries, recorded by air photography.

A Site visit revealed quantities of medieval and post medieval pottery beneath a barn.

Watching Brief at Abbotts Hall Farm, Great Wigborough. A previously unrecorded red hill, of possible Iron Age date, was observed and a probable medieval midden of oystershells was recorded near Salcott.

The chancel was lengthened by a few feet, probably in C14.
