Bunker B-S 4 Lány

Why visit

Bunker B-S 4 Lány was part of the line of fortifications Czechoslovakia built in the late 1930s to resist Nazi Germany. The original was stripped and left to decay.

Since 2011 a group of volunteers, some of whom played here as children, have rebuilt it from original plans and photographs. Today it shows how a bunker crew lived and fought on the eve of the Second World War.

What to see

• Firing rooms: original heavy machine guns and an anti-tank gun, with the guides explaining how they worked.
• Armoured observation posts: and the system the observers and gunners used to talk to each other.
• Engine room: with a working diesel generator.
• Underground quarters: the crew’s living rooms and emergency stores.
• Outside: restored anti-tank and anti-personnel barriers of concrete, steel and barbed wire.

Plan your visit

The bunker can only be seen on a guided tour of about 45 minutes, led by the volunteers. Tours run on Saturdays, every full hour from April to October and less often in winter; for other days, contact the museum in advance.

Tours are in Slovak, and in English when an English-speaking guide is available; otherwise there is an audio guide. Paid admission.

The bunker has narrow passages and stairs and is not wheelchair accessible. It is a cycle ride along the Danube embankment from the centre; on foot it is about 35 minutes from the Lanfranconi Bridge, and drivers can park by the Berg border crossing.
