Excavated in Spring 1978, which defined a possible timber Saxon church under the C11 unicellular apsidal masonry church.

The keep became ruinous early in the C17. Changes were made to the structure in the mid C18.

Upper part of the tower fell probably early in the C17.

Only church in Colchester mentioned in Domesday Survey.

Parish Church of St Edmunds, also referred to as the Parish Church of St Edmund King and Martyr. The earliest masonry dates from the C12-C13 but much of the structure is C14-C16.

17th century house

11th century (c.AD 1078) Norman Castle Keep built on the foundations of the Roman Temple of Claudius and Bailey defences. The keep was built in at least two main phases and its initial form consisted of a single storey stone keep with crenellated parapet wall. During the early 12th century, the keep's outer walls were raised by at least one storey and a fore-building was added on the south side to protect the main entrance. A barbican replaced this in the 13th century. The castle's earthwork defences consisted of an upper and 'nether' or lower bailey bank and ditch (to the north, and downslope to the town wall) with at least one entrance in the upper bailey's south-west corner, occupying c.5.7ha. in total area. The upper bailey defences had been built by 1101. The northern and eastern arms of the upper bailey defences survive as landscaped earthworks within Castle Park. The southern arms lies just to the north of the High Street, and the western arm, below or just to the east of Maidenburgh Street. The nether bailey is possibly part of a second phase, of the late 12th century. The southern end of the eastern arm of the nether bailey survives as a landscaped ditch in Castle Park. The western arm lies below or just to the east of Maidenburgh Street. A masonry chapel and domestic buildings stood to the south of the keep. The keep was partially demolished by John Wheeley in the 17th century.
