“Hadrian’s Wall was built by the order of the Emperor Hadrian, following his visit to Britain in AD 122. 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.”

The outer walls of the fort at Birdoswald, known in Roman times as Banna, stood 4.5m tall, a height similar to that of Hadrian’s Wall itself. The fort had East and West gateways onto the Military Way, the main road connecting all the forts along the length of the Wall. It was occupied by Roman auxiliaries from approximately AD 112 to AD 400, and comprised a headquarters building, granaries, barracks and an exercise building.
The longest remaining continuous stretch of Hadrian’s Wall can be seen at Birdoswald.
