Caister-on-Sea is a Roman fort and Saxon settlement located in Norfolk, England, occupying a strategically important position on the East Anglian coast. The Roman fort, known as Gariannonum, was constructed in the third century as part of the Saxon Shore defensive system and was garrisoned to protect against coastal raids. The site was subsequently reoccupied during the Saxon period, demonstrating continuity of settlement at this location into the early medieval period. Archaeological investigation and fieldwork have revealed structural evidence of both the Roman fortification and later Saxon occupation, making the site significant for understanding Roman military strategy and post-Roman settlement patterns in eastern England.
