Hadrian's Wall was built by the order of the Emperor Hadrian, following his visit to Britain in AD122. His purpose was to mark the boundary of the Roman Empire and divide the `civilised` world from the tribes beyond or, as Hadrian`s biographer put it, "To separate the Romans from the Barbarians". It was planned as a continuous wall with a milecastle every Roman mile (1.48 kilometres) and two turrets equally spaced between each milecastle. The Wall, with its defensive ditches and large forts, stretched from coast to coast, a distance of 80 Roman miles (approximately 120 kilometres or 75 miles). It formed the northernmost frontier of the Roman Empire.

Hadrian's Wall is a World Heritage Site, designated by UNESCO.
