The XIIb/565/A-160 is a military bunker located in Czechia, near the coordinates 50.155712, 17.391047. This structure appears to be part of the Czechoslovak border fortifications system built in the 1930s as a defensive measure against potential German aggression. The bunker's designation follows the Czechoslovak fortification nomenclature system, where 'XIIb' likely refers to the fortification sector, '565' to the specific object number, and 'A-160' to a particular variant or modification.
These border fortifications were constructed between 1935 and 1938 as part of Czechoslovakia's strategic defense planning during the interwar period.
