Czechoslovak fortification – Block Šatov MJ-S 3 “Zahrada”

Almost all European countries started at the end of 1920s or beginning 1930s with preparations for new war. The experience from WW1 showed, that building of huge fortifications on the boarder could be a good strategy. In 1929 France began to construct the famous Maginot line, one of the biggest fortifications in the world. Approximately in same time started with building of Stalin´s line also Soviet Union, s little bit later, in 1933 joined this trend also Poland and in 1935 Netherland.

Czechoslovak republic decided, after the long discussion, to build a huge fortification system in 1935 – alternative was to develop mobile and well motorized army instead, but this solution was found as too expensive and country had no sources of fuel (moreover ambitious project like building fortification allowed to help the problem with unemployment). That year travelled a group of army officers to France, to get an inspiration from Maginot line, later came French experts to Czechoslovakia to help with construction. The basic used pattern practically was practically copied from French Maginot line, but during the time some innovations were developed.

The problem of this plan was obvious – border of the country measured 4 120 km, 1529 km shared Czechoslovakia with Germany – after annexation of Austria even 2 117 km. But Poland nor Hungary weren´t good neighbors too, the only safe border was about 200 km with Romania. Securing of such a long boarder was for small state with big German minority quite a big challenge. Czechoslovak government planned to construct 15 463 light and 1276 heavy fortification objects in ten years long period. In year 1935 signed republic also alliance with France and Soviet Union.

The strategy of Czechoslovakia presumed, that army could hold this “Benes line” (named after the foreign minister and later president of state Edvard Beneš) until the French and Soviet army respond with attack against Germany. Because of later signification of Munich Agreement in 1938 and following occupation of country the fortification system was never finished – just about 20 % of bunkers and forts were really finished and prepared for war.

After the World war II. and communist takeover of the power in state, some of the forts and bunkers were reactivated against the “imperialistic” enemy from the west. Some new weapons (mostly soviet) were installed and the system served until late 90s.

Block  MJ – S3 “Zahrada” in Šatov


Visited object called Infantry Block Šatov “Zahrada” is located on the Austrian border and it was built during the summer 1938. The block was designed for crew of 34 men, it had two floors with all necessary equipment, so the soldiers could stay inside for couple of weeks. Original weaponry represented two anti-tanks cannons vz. 36 with caliber 40 mm, and two heavy machine gun-twins vz. 37. The closest surrounding of the object should be defended with light machine guns vz. 26 and hand grenade holes. Two observatories allowed to watch the border and inform the heavy artillery about movements of enemy. They were also armed with light machine guns.

Till the beginning of the war it was not fully equipped and not really prepared for conflict. Nevertheless Šatov was used during the year 1938 in short fights with German paramilitary organisation Freikorps. After the occupation of border area by German army was the object deactivated and damaged.

The army finished the construction and reactivated the object in year 1946 for case of the World war III. Since 1960 used the object antitank cannon from soviet tank T-34/85 (used under the sign PvK vz. 44/59), which served here until 1999. After Czech admission to NATO was the object closed and rebuilt to museum.
