Heddon on the Wall, Hadrian's Wall Photographs

Hadrian's Wall was built by the order of the Emperor Hadrian, following his visit to Britian in AD122.

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..
