Munich’s most exciting underground exhibition space—the Arcade for Interdisciplinary Art—shows multimedia works by free-thinking and creative artists such as Ayzit Bostan, Pollyester, Florian Süssmayr, and Mirko Borsche. It’s open around the clock and admission is free. The 17,000 sq. ft. pedestrian underpass under the intersection of Altstadtring and Maximilianstraße is an open, yet protected area and provides space for experimental ideas right in the heart of the city.
