There are constructions on either side of the wall. Regularly spaced, guardhouses (semicircular huts) were used to house a sentry in the event of inclement weather and were certainly covered with a roof in branches or tiles. The huts attached to the wall, housed the units but also the equipment and provisions. On the most isolated places of the plateau, the pens served as warehouses for food and fodder for mules transporting water and provisions.
