The Antonine Wall is the northernmost boundary of the Roman Empire. An exercise in military engineering nearly 2,000km from Rome, it was designed and built explicitly as an example of the might of Emperor Antoninus Pius. Though half the length of Hadrian’s Wall, its southern ancestor, it deserves recognition not only as a high water mark of the Empire, but as a marvel of engineering in its own right.
Today’s military engineers receive their training largely through university degrees, often at military-focused schools such as Norwich University’s school of civil engineering. Not so the Roman military engineer, part of the legion’s immunes class. Raised from the munifex classes (rank and file soldiers), the engineers who built Rome’s far-flung network of roads, fortifications, and many of its more distant cities (a means to keep them busy and productive during times of peace) learned on the job.
