Rome : L'armée des bâtisseurs

All throughout the Gallic Wars, Caesar’s army drew on the power of its military genius to defeat the Gauls. Once the territories were conquered, the technical skill of the Roman legionnaires was used to build monumental infrastructures like the impressive stone forts that served to protect the borders of the empire. An instrument of both land conquest and territorial planning, the Roman legion proved to be Rome’s most precious asset: a formidable army of builders. (Mediawan)
