Prior to the Roman invasion of Cornovian territory in 47 AD the most significant Cornovian hillforts known were those at Titterstone Clee near Bitterley, being the only one excavated to date, Chesterton Walls near Romsley and Bury Walls near Weston-under-Redcastle. Other hillforts of Iron Age Cornovii include the Wrekin hillfort near Wellington, Caynham Camp near Poughnhill and Old Oswestry. All of these camps are in the county of Shropshire but there was another significant settlement at the Breiddin hillfort in Powys.
