The Czechoslovak government built a system of
border fortifications
from 1935 to 1938 as a defensive countermeasure against the rising threat of Nazi Germany. Infantry blockhouses and military fortress are a legend in the territory of Czech Republic.
Heavy fortified installations - The heavy fortified installations with infantry blocks were built in the border sections with high defence priority. They were solid, mostly two-storey constructions which were armed with machine guns as well as with anti-tank guns, if necessary with mortars, too. The typical characteristics of these blocks were the armoured cones and cupolas which served for the observation of the battlefield. Other tasks were the fire control and the command of the machine guns. In case of war each infantry block was able to operate independently. Besides other facilities each infantry block had its own well, filter room and engine room, in which the electric power was generated. The infantry blocks were individually shaped to the corresponding terrain and constructed in accordance with their combat tasks. They differed in their dimensions, outlines, wall and ceiling dimensions, armament and garrison. Nevertheless they consisted of standardized construction and design elements. For a usual infantry block about 1300 to 1500 m3 of concrete and up to 120 tons of steel reinforcement were needed. They could stand artillery shelling up to calibre 305 mm. Until September 1938 228 heavy independent blocks were structurally finished.
The infantry blockhouse N-S 71 "V sedle" was, in connection with the construction of the anti-nuclear shelter Hanicka, reconstructed under the code name Kahan III in the years 1986-1989 to become the connecting centre of the secret State Security Ministry of the Interior.
