SDO9661 - 'Excavations at County Hall, Colliton Park, Dorchester, 1988' Proceedings of the Dorset Natural History and Archaeological Society

Interim report on excavations at County Hall in advance of the construction of a new computer wing and car-parking facilities in 1988. County Hall, Dorchester lies in the north-west corner of the Roman town of Durnovaria within Colliton Park. Remains of a number of Romano-British buildings have previously been recorded in this area. The earliest Romano-British activity is represented by three field boundary ditches of 1st century AD date. These pre-dated construction of a north-south street which was a component of the early town plan. The western edge of this street was defined by a gutter with a number of 1st and 2nd century AD pits lying to its east. In the 2nd century the street seems to have fallen into disrepair but was later remetalled to a lesser width in the later 3rd century. Quarrying activities at this time may have been associated with construction of the early town ramparts. An oven or furnace to the west of the street was later abandoned and became sealed below a 4th century building, probably of a residential function. The bodies of two small infants were buried under the floor. A ditched enclosure established to the east of the road contained a corndrier which produced only clean grain, indicating crop processing took place elsewhere. Probably in the 4th century large, barn-like building was constructed to the east of the street. This seems to have been associated with outhouses, sheds, and fenced enclosures and suggests a semi-rural position. After its abandonment the building was allowed to decay, becoming filled with 4th century rubbish, and was not substantially robbed. The site seems not to have been occupies in the post-Roman period, perhaps until as late as the 13th century. During the 17th century Colliton House was constructed and the park laid out.
