Limes

In the context of general knowledge, "limes" refers to the ancient Roman fortifications that marked the boundaries of the Roman Empire. These structures included walls, watchtowers, and roads, serving both as defense against invasions and as control points for trade and movement. The limes often followed natural landscapes, like rivers and mountains, creating a strategic barrier. They played a key role in the administration and security of the empire, symbolizing its extent and reach. Today, many remnants of these limes can still be seen, highlighting the engineering prowess and organizational capabilities of ancient Rome.
