The Czechoslovakian republic has created a network of fortifications along the border due to the threat from Germany in 1935. Those fortifications were designed to protect the key points of eventual invasion from Germany, Hungary, and Poland. Chechoslovakia was able to conduct a defensive war and to wait until the Allies including Great Britain, France, and the USSR will come.
After Adolf Hitler who claimed the occupation of Sudetenland, populated by ethnic Germans has taken the power in Germany, the Czechoslovakian government has taken the decision to start a defensive strategy. Some defensive construction was built quickly and after the negotiations with the French government, massive construction of defensive fortifications was started.
French have changed the philosophy of construction defensive fortifications in Czechoslovakia and in 1936 long term firing points, as well as huge blockhouses, appeared there similar to Maginot line. The first stage of construction should be done in 1941-1942 according to the plans and the end of construction should be done by the beginning of the 1950s.
By September 1938, 264 blockhouses and more than 10 000 longterm firing points were built. After the Anschluss of Sudetenland by Germany, Germans used these objects to test and develop new firing arms and tactics. Germans used this strategy against the Maginot line and Belgian forts. After the fall of Benelux countries and France, Czechoslovakia fortifications were blown and the stones were used to build Atlantic rampart.
In 1945 Germans repaired those fortifications to use them against Soviet advance from 17 to 26 April.
After the war, multiple armored parts were sent to recycling as there was a deficit of steel. Moreover, those fortifications were unuseful as they have lost their strategic role.
Some under terrain constructions were used for the army needs or became warehouses. Some bunkers were destroyed. The rest was left or became museums.
