Near Panzerwerk 717 are two tobruks of Regelbau 58c. These were probably connected to the large Panzerwerk by trenches. The Tobruk is located at a strategic point to provide extra support in the event of an attack by enemy infantry. Regelbau 58c is distinguished by the fact that it has a smaller entrance to the gun position. To enter, one must stoop, whereby a Regelbau VF 8 Ringstand (Eng. Tobruk) can be entered almost upright.
Visit
From the Fortification museum, walk along the road past the monument and find the Tobruk on your left in the field.
