On exposed hilltops, positions with anti-aircraft guns (flak) were built for air defense based on the model of the Siegfried Line. A system of crew and ammunition bunkers, command posts and gun posts covered the Schwedenschanze and the Rosenberg to the northeast. Other bunkers were located next to the L10 in the direction of Berndorf and in the Kyllerhöhe development area south of the Schwedenschanze.
Over 20 individual objects were built in the so-called "full expansion", i. H. all buildings were concreted throughout. The centerpiece of the system were heavy 8.8 cm anti-aircraft guns, which were located in open gun positions. There were also several crew bunkers (F stands), each of which served as a shelter for up to 18 soldiers. Simple, concreted ammunition bunkers (M-Stand) served as storage space for the ammunition. Machine gun loopholes served as a ground defense for the battery. In addition, there were systems for an independent water supply and an open device position with distance measuring devices.
The purpose of this facility was, on the one hand, the direct shooting down of aircraft penetrating from the west. On the other hand, the systems should force the aircraft to fly at greater altitudes and thus reduce their maximum range and bomb load. However, the systems could never live up to their demands. Further systems are on the way to Zilsdorf and Betteldorf, as well as on the Eselsberg near Dockweiler. After the war all bunkers were blown up by the Allies.
