This fortified city or "castrum" of the Later Roman Empire closed off the high point of the Sarge plateau by forming an irregular quadrilateral of 450 m in length by 200 m in width.
The 1,300 meters of its perimeter closed in an area of nine hectares that would become for 15 centuries the historic center of city of Le Mans.

These blocks are occasionally decorated with chiseling or brocaded bossage forming lines in the arcs of a circle.
