The Pharaos (lighthouse) of Alexandria, the Collosseum in Rome, the Persian and Roman road systems, and many other large structures are only a few examples. Until the Industrial Revolution there were only two kinds of engineers. The military engineer built such things as fortifications, catapults, and, later, cannons.
