 In June 2009 the original building closed its doors, and the museum began relocating into the U-Tower, where it reopened under the new, shortened name Museum Ostwall in October 2010.The seven-storey tower, a former Dortmund Union brewery and warehouse, played a key role in the Ruhr Area's rebranding as "Culture Capital of Europe 2010" ("RUHR.2010 – Kulturhauptstadt Europas").The museum reopened with the special exhibition "The Museum as Power Station" ("Das Museum als Kraftwerk").
