The features provide information about the construction of the fort
walls. An example is the collapsed wall of the numerus
The wall was discovered almost completely intact. It was 4.75m (16 Roman feet) high from the ground to the cornice, plus the c. 70cm deep foundation, and 1m deep. The external front of the wall consisted of roughly 20cm high stone blocks and the back side of stones up to 15 cm long. The gaps between the stone blocks were filled with stone scraps that were sealed with lime mortar. This provided a great deal of stability.
Above the cornice was the parapet walk protected by the battlement parapet topped by crenellations. Above the crenellations were the capstones. At the Main Limes many of these capstones were made of red sandstone, just as they are displayed in the Römermuseum Obernburg.The front side of the fort wall was plastered and/or finished with a limewash. Occasionally, red lines were added to imitate the masonry joints. A reconstruction of a painted fort wall can be seen at the Saalburg museum.
