They are walls built to mark the boundary of an empire and to keep out invading tribes the imperial power thought to be barbarians. The Great Wall marked the boundary of the Chinese empire. The barbarian tribes were the Mongolians. Hadrian's Wall marked the boundary of Roman Britian. The barbarian tribe was the Picti.
