After visiting the interior of the fort, you should head north on the main road to Wissembourg. At the first road intersection, turn left – west – and proceed until the road makes a moderately sharp turn around a small hill. Here amongst fields today you can still see the turrets of the combat blocs. Blocs 1 and 6, the infantry casements, are found on the outside while the artillery blocs are in the middle. Barbed wire surrounded blocs when the fort was operational and the blocs were surrounded by anti-tank barriers, as well. If you turn right at the intersection mentioned – towards Hunspach – you will find a couple of infantry casements that were part of the Hunspach defensive positions, the next step along the Line to the east of Schoenenbourg.
Schoenenbourg had six combat blocs, two of which - Blocs 1 and 6 - were infantry casements which provided protection for the surface levels of the combat blocs. Bloc 2 provided more machine gun protection against would-be attackers. Blocs 3 and 4 had twin 75mm artillery turrets while Bloc 5 had twin 81mm howitzers which were set at a fixed elevation – shell range was modified by using different charges. The 81mm howitzers could range their fire out to 3.5 kilometers while the 75mm guns could fire out to 9.5 kilometers. The gun turrets would pop out of the ground to fire and then retract leaving only a heavily armored turret top showing on the ground surface between fire missions.
Just behind the combat bloc areas, you find the command centers for the fort – one for the fort’s infantry – something that was lacking at the Belgian %LFort Eben Emael - one for the control of the artillery and one for overall command of the fort. Artillery spotters would send information here and artillery officers would then decide which artillery bloc would respond and how.
