Infantry log cabin (bunker) B-S 6 "Willow" of heavy fortification of Bratislava bridgehead in Petržalka was built at the turn of 1934-1935. It was part of the defense system proposed by General Šnejdárek, commander of the Provincial Military Command (ZVV) Bratislava.
Later, the infantry log cabin was incorporated into a unified Czechoslovak defense system, in which other infantry bunkers and additional objects were built in 1936 and 1937 in Petržalka.
This bunker is atypical as seen in the photos. The ground plan of this one-storey building resembles the letter "T", but with two feet (or the letter "π" of the Greek alphabet).
The bunker hosts various events during which you can see it.
