The Roman town of Durocornovium was located at Covingham, less than a mile from South Marston, on the junction of two Roman roads, the Ermin Way & the road south to Mildenhall (Cunetio).
The Ermin Way connected London via Silchester to Cirencester (Corinium), the second largest Roman town after London.
Durocornovium was founded in the First Century as a military camp but it became a merchant town covering more than sixty acres & having a population of several thousand at its peak in 350AD. Excavations were made in the 1970’s and the site of the Mansio (an inn) is a Scheduled Monument. See The Romano–British Small Town at Wanborough by A S Anderson et al.
It is likely that Durocornovium was supplied with agricultural produce by farms & villas in the surrounding countryside.
The Dobunni tribe accepted Roman occupation & embraced a Romano-British culture.
From the 1st to 4th Century AD, South Marston is likely to have been a large Romano-British farming settlement.
The following is a brief list of where Roman features and finds have been found in the parish, with links to more detailed information.
