May through September is best, with the Bundesliga season running August to May for football pilgrims. Match-day at Signal Iduna Park (capacity 81,000, Europe's largest standing terrace) is memorable. The German Football Museum on the central square covers the wider story. The Westfalenpark, the U-Tower, and the lakeside Phoenix See give an honest sense of how Ruhr cities have transformed.
Most central shops close Sundays. The city center is functional rather than pretty, Allied bombing in WWII and post-war rebuilding left little of the medieval town. Match days bring huge crowds and limited transport. Book hotels months ahead for big games. A route through Dortmund needs enough margin for hours and delays to change. In Dortmund, Sundays, holidays, traffic, queues, or cross-town transfers can change the day quickly.
