This book reports on excavations on the Camp Hill promontory fort at Lydney, Gloucestershire, undertaken by Mortimer and Tessa Wheeler in 1928-9. The hillfort was established shortly before the first century BC. During the second and third centuries AD it was occupied by a Romano-British population engaged, at least partly, in iron mining. Excavations focussed on a temple, dedicated to the god Nodens, built within the fort, and associated with this were a guest house (mansion), baths and other structures. Structural details of these buildings are described, and specialist reports describe the worked stones, metalwork, pottery and other finds, recovered by the fieldwork.
