Field investigations in the large field to the west of the temple site.

Roman building within the temple precinct on the Royal Grammar School playing field, excavated in 1947.

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.

3rd century Roman Temple at St Helena School, recorded during excavations in 1935.

Immediately before the S front of the temple and castle, 59ft from the latter and 92ft from the presumed face of the former, was uncovered a large well dressed stone in the centre of which was a round hole 6.5" in diameter..

Possible Roman temple, St Mary's Hospital, Pope's Lane, Colchester.

Temenos enclosing Gosbecks Romano-Celtic temple complex (MCC2849). The large walled enclosure or temenos (c.2.65ha. in area), enclosing the temple, abutted another large (c.4ha.) walled area to the east, to the north of the theatre (MCC2831) and north-east of the site of Cunobelin's farmstead (MCC7044).

Roman drain, south of the Temple of Claudius.

Roman wall foundation, aligned N to S, discovered during a watching brief at the Conservative Club, Maidenburgh Street (rear of 107 High Street) in 1975. Possibly the west wall of the temple precinct MCC1544, but this is quite uncertain.
