The Museum Ostwall is a museum of modern and contemporary art in Dortmund, Germany. It was founded in the late 1940s, and has been located in the Dortmund U-Tower since 2010. The Museum Ostwall displays art from the twentieth century. It was opened in 1949 as the first new museum to be founded in the only recently established Federal Republic of Germany. In 2010, the museum was moved to the Dortmunder U. The Metropolis Ruhr is tasked with constantly reinventing itself. Art and culture help to define a location. This is a task to which the Museum Ostwall has dedicated itself. A task which began with museum founder Leonie Reygers. A key element of her design was to exhibit art and culture in an accessible place which was inviting and open to all citizens. For this reason, she had amateur art and museum-based educational work with children particularly at heart when designing the museum, an approach which earned her the Federal Cross of Merit. In accordance with this attitude, as of 2019, the Museum Ostwall's permanent exhibition can be visited for free.
