Bunker B-S 7 Cvičiště (“Training Ground”)

B-S 7 was the first bunker in Petržalka to have its concrete shell completed, dating from 1933. It was part of the “Šnejdárek Line” (the first bunkers built to defend Petržalka against Hungary, commissioned in 1933–35 by Army General Josef Šnejdárek). These were smaller structures, with machine-gun armament and modest equipment. B-S 7 stands in a field near bunker B-S 8 and can be seen from the former border-guard road known as the signálka.
