Thank you to Mike Anderson for publishing my article on the Antonine Wall.
Completed in the year 128 C.E., Hadrian’s Wall was one of the most famous civil engineering projects undertaken by the Roman Empire. The wall ran a distance of 73 miles (117.5 kilometers), crossing the English countryside from the waters of Solway Forth to the mouth of the River Tyne. It took the effort of three Roman legions working over the course of six years to complete, and required a garrison of more than 10,000 men to guard its length. Built by the Emperor Hadrian, many people believe this wall represents the limit of Roman expansion as well as the northernmost reach of the Empire.
