A military bunker located near Lány, Slovakia, situated in the Bratislava region. This structure is part of the extensive Czechoslovak fortification system built in the late 1930s as a defensive measure against potential German aggression. The fortifications were constructed rapidly between 1935 and 1938, representing a significant engineering effort by the First Czechoslovak Republic to protect its borders.
These bunkers formed part of a comprehensive defensive line that stretched along the country's borders, designed to withstand modern warfare conditions.
