Bunker B-S 6 Vrba Czechoslovak army museum

A Rare Pre‑WWII Defensive Structure

Bunker B‑S 6 Vrba is one of the oldest fortification structures of the First Czechoslovak Republic, built between 1934 and 1935 as one of nine atypical “Old Objects” constructed exclusively in Bratislava’s Petržalka district. The bunker has retained its original atmosphere and architectural features, offering insight into the military engineering of the pre‑World War II period. As the only museum of its kind, it presents authentic equipment, preserved interiors, and digitized historical documents that illustrate the defense of Bratislava.

A Museum Bringing Soldiers’ Stories to Life

Today, B‑S 6 Vrba functions as a museum dedicated to the history of Czechoslovak border defenses and the events that shaped the protection of the capital. Visitors encounter rare artifacts, archival materials, and exhibits that reveal the stories of soldiers, technologies, and wartime developments connected to the bunker. Its location in Petržalka places it within the only fully preserved defensive section of the former Czechoslovak fortification line, making it a significant historical site for understanding the region’s military past.
