Hadrian, Building the wall, Ancient Rome

Very Dry, but informative Hadrian, Building the wall: In 122 C.E. Hadrian ordered a mighty frontier system to be built across the north of Britain. The result was Hadrian's Wall, a 73 mile barrier stretching from the Solway Firth on the west coast of Britain to the River Tyne on the east coast. © Trustees of the British Museum
