Mur d'Hadrien, Hadrian Wall

Hadrian's Wall was constructed, between AD 120 and 128, coast to coast from Bowness on Solway, just west of Carlisle, to Wallsend on the River Tyne estuary- a distance of 73 miles, (which the author can verify, having walked the whole length of the wall in 1972). Hadrian's Wall is recognised as one of the most important Roman remains in the United Kingdom, having been declared a World heritage Site.
