HADRIAN'S WALL

Hadrian's Wall was built to prevent the irruptions of the Scots and Picts into the northern counties of England, then under the Roman government. It extended from the Tyne to the Solway Firth and was eighty miles long, twelve feet high, eight feet thick and supplied with watchtowers. It was built in 121 and repaired and strengthened between 207 and 210.
