Usk (Burrium) has long been considered a Roman site. Its identification as a pre-Flavian military site was made by Boon, following his reassessment of material recovered in the nineteenth century. Subsequently a series of excavations was undertaken between 1965 and 1976 by Professor W.H. Manning on behalf of University College, Cardiff and the Department of the Environment (later the Ancient Monuments Branch of the Welsh Office). Since 1975 work in Usk has been carried out by the Glamorgan-Gwent Archaeological Trust.
