A centenarium, plural centenaria, is a type of ancient Roman fortified homestead with farming facilities and garrisoned by limitanei, placed in the Limes Tripolitanus (the limes of Roman Libya). The Limes Tripolitanus contained more than 2000 of these fortifications, connected to create a defensive system against desert tribe raids.
