Castra

In this episode, we explore the Roman castra, the highly organized military forts that served as both temporary marching camps and permanent legionary bases across the empire. We look at how these fortified sites followed a standardized rectangular grid, complete with walls, ditches, gates, and the central principia, while carefully planned streets connected barracks, hospitals, and workshops to support discipline, efficiency, and hygiene. The episode also highlights the daily lives of the soldiers who trained, worked, and ate within these secure spaces, and examines how civilian settlements known as canabae or vici often grew outside the walls to serve the troops. By tracing their strategic design and lasting influence, we reveal how many Roman castra became the foundations of modern European cities.
