'''Hadrian's Wall''', also called the "Roman Wall" or "Picts' Wall," was a [[border wall]] built by the Romans across [[Britain]] in the 2nd century AD to mark and defend their northern frontier from [[Picts|Pictish]] incursions (an alternative theory is that is was not primarily a defensive structure but a tax barrier). The [[Roman Emperor]] [[Hadrian]] visited Britain in AD 122, and the wall began construction around the time of his visit, and upon his orders. | '''Hadrian's Wall''', also called the "Roman Wall" or "Picts' Wall," was a [[border wall]] built by the Romans across [[Britain]] in the 2nd century AD to mark and defend their northern frontier from [[Picts|Pictish]] incursions (an alternative theory is that is was not primarily a defensive structure but a tax barrier).
