Lock point Stadel

The barrage at Stadel was a barrier built by Border Brigade 6 of the Swiss Army during the Second World War from 1939 , as part of the barricade Siglistorf - Thalmühle in the Bachsertal - Stadlerberg - Rotenbrunnen on the Strassberg near Stadel - Schachen near Glattfelden - Wagenbrechi between Glattfelden and Rorbas as the third line of defense behind the Rhine to stop and delay an opponent's advance. The lock point is considered a military historical monument of national importance.

history

Immediately after the outbreak of war in 1939, the construction of the barrage at Stadel on the plain between Rietwisen and Steigenhalden, 500 m north of the village center of Stadel, was tackled by several construction companies under the direction of the Bern Fortifications Office (BBB). A long anti-tank obstacle was created with seven street barricades and four infantry units as a line of defense.

With the combat model of the infantry in restricted areas, the enemy should be stopped at the main obstacle. Obstacles could be created by explosive objects, terrain obstacles, barricades, minefields or combinations of these elements. In order to prevent the enemy from bypassing them, such obstacles were anchored in strong terrain and should be equally effective for all possible directions of attack. Weapons that were supposed to act directly on the obstacle to defend themselves had to be protected in perfectly safe bunkers. Section troops could only survive the massive enemy preparatory fire in concrete shelters.

With Army 61 , the old barriers were strengthened with the newly developed anti-tank obstacle 66 (GPH 66) from the 1960s and around two dozen modern shelters (spherical bunker "Kubu" U4, nuclear protection shelter ASU) were dug in front of and behind the anti-tank obstacle .

From 1980, the obstacles to the redoubt in the Alpine region were reduced and those in the Central Plateau were condensed. The important barrage Stadel north of Kloten Airport was expanded into the so-called "Russenring": the four infantry bunkers were rebuilt and the refueling obstacles replaced.

With the advent of nuclear weapons, the large fortifications had become vulnerable and too expensive because they required a large number of operating personnel and full-backs. The development of stand-off weapons and intelligent ammunition that seek their own targets also endangered the smaller, old-style factories. Nevertheless, correctly installed fortress weapons offered the advantages of a higher level of protection, faster readiness and greater fire effect. This led to the fact that the fortress artillery was built into so-called “monoblocks”. "Monoblocks" were small, heavily protected bunkers that were built using opencast mining and then made completely safe with sandwich-like protective layers. Bollen stones were supposed to absorb the force of an explosion from impacting grenades. The monoblock bunkers flanked the obstacle, were covered with the narrow firing area from the enemy direction and could only be combated late.

In 1995, three towers of the Centurion 55/57 main battle tank were installed in "monoblock" Centi bunkers in two infantry bunkers . The 10.5 cm guns with a range of up to 2 km were never shot. The equipment of this type of system consisted of the armored turret, a laboratory room below with a workbench and ammunition niche, a niche with an emergency power generator, a fuel store in canisters, simple accommodation with three beds and ventilation with a filter.

With this, Border Brigade 6 received 95 modern anti-tank guns with the latest thermal imaging target devices 90 (WBZG 90) before it was disbanded with the army . With the Army XXI , the Centi bunkers were no longer assigned any troops from 2004, after which they were released from secrecy.

The blocking point consisted of around 40 objects and received fire support from mine throwers.

today

The main criteria for the national classification of this lock from the Second World War were the quality of the various objects and the complete modernization in the post-war period.

After being taken over on a rental basis by the Military History Society of the Canton of Zurich , the Centi Bunker in Zurich was opened for viewing in 2009. The barrier is now fully leased to farmers, is managed according to the guidelines of ecological compensation and is integrated as a networked element in the landscape development concept.

Blocking points Regensberg and Buchs

In the Zürcher Unterland , three staggered defense belts were built from 1935 as part of the delay area of Unterländer not engaged in active service . The third belt at the level of Stadlerberg-Bülach and to the east of it belonged the barricade barn with heavy artillery and anti-tank barriers as well as the medieval town of Regensberg with machine gun position within the preserved historical ramparts of the city wall (southeast half of the horn factory of the former Dielsdorf gate).
