Bunker Ulmenwall, Underground music venue in Bielefeld, Germany.
Bunker Ulmenwall is an underground music venue in Bielefeld located at the base of Sparrenberg, offering roughly 200 square meters of space with a central stage area. The concrete structure holds about 199 people and hosts regular concerts and music events.
The structure was originally built in 1930 as a medical facility before later being transformed into a performance space. This repurposing allowed the venue to develop into an established music center that received the WDR Jazz Award in 2018.
The space functions as a meeting point for musicians and artists who perform experimental shows and jam sessions here. Visitors experience a mix of established and emerging talent coming together in the intimate underground setting.
Access is from Ulmenwall street and the structure is embedded in hillside terrain, requiring careful attention to locate the entrance. Visitors should be aware this is an underground space with limited natural light.
The concrete walls of this underground structure earned it the nickname Toaster among musicians due to their specific sound properties. This architectural feature influences the acoustic quality of every event held here.
