Excavations within Castle park were initiated as part of a conference held to celebrate the nineteenth centenary of the foundation of the Roman Colonia at Camulodunum. The conference took place between the 4th and 7th July. Excavations were undertaken by M.Alwyn Cotton and Miss.K.M.Richardson under the consultative advice of Sir Mortimer Wheeler, Professor Hawkes and Rex Hull. The volunteer labour force was led by Col. R.J. Appleby. The point chosen for excavation was in the north east corner of the Norman bank to the north of the Castle, where it is at it highest and where a corner of masonry was exposed about half-way down the bank. Two wide trenches were cut into the northern and southern sides of the earthwork. In addition the exposed masonry at the corner was cleared to its foundations. The Roman structures uncovered consisted of : two streets, the walls and floors of a terraced masonry building, a later demolished wall and a sealing layer of earth which represented the occupation in the area from the late Roman times to the arrival of the Normans.<1><2><3>
