Caister Roman Site is a Roman Saxon Shore fort, located in Caister-on-Sea, Norfolk, England. It was constructed around AD 200 for use by units of the Roman army and navy, and was occupied until around 370-390 AD. This fort was possibly known as Gariannonum, although the single record that describes it as such may also mean the Roman site at Burgh Castle.
