Walk east of the city center and a strange black cylinder rises above the trees: the Gasometer Oberhausen, 117 meters tall, a former industrial gas-storage tank that should have been demolished when the steelworks shut down. Instead it became one of the most extraordinary exhibition spaces in Europe. Artists install work inside the column - sculptures, projections, installations that exploit the cathedral-scale void. Visitors take an elevator to the roof and look out over the Ruhr conurbation, the river Emscher snaking below, the receding industrial geometry. It is the anchor point of the European Route of Industrial Heritage in this corner of the region. The Gasometer is what Oberhausen learned: you do not always tear down the thing that defined you. Sometimes you let it become something else.

Across the canal from the Gasometer sits CentrO, opened in 1996 on the cleared ground of the old Gutehoffnungshuette steelworks. When it opened it was the largest shopping mall in Europe. The reinvention strategy was naked: knock down the symbol of the old economy, build a temple to the new one on the same dirt, employ the children of laid-off steelworkers in retail. Whether it has worked is contested. Oberhausen's unemployment rate was 10.4 percent in July 2020, well above the German average. But CentrO drew tens of millions of visitors a year and pulled a tourism industry into existence in a city no one had previously thought to visit. The Aquapark, the Sea Life aquarium, and the Marina followed. The city now markets itself as a destination.

Since 1954, Oberhausen has hosted the International Short Film Festival - one of the oldest events of its kind in the world. In 1962 a group of young German filmmakers used the festival as the launching pad for the Oberhausen Manifesto, declaring the old commercial German cinema dead and announcing the birth of New German Cinema. Fassbinder, Herzog, Wenders, Kluge - the entire generation that would put postwar German film on the international map - traces its founding moment to a manifesto signed in this Ruhr city. The 1982 Deutscher Filmpreis went, twenty years later, to the group that had written it. The festival still runs every May, drawing filmmakers from around the world to a city most of them had to look up on a map.

The Turbinenhalle is what the name says - a former turbine hall, now repurposed as a venue. Each March, the German independent wrestling promotion wXw stages the 16 Carat Gold Tournament there, drawing fans from Japan, the United States, the United Kingdom, and across Europe to watch three nights of wrestling considered among the best in the world outside the major American promotions. The Rudolf Weber-Arena has hosted UFC 122 in 2010 and the PDC Unibet European Championship of darts in 2020. Football club Rot-Weiss Oberhausen plays at the Niederrheinstadion on the banks of the Rhine-Herne Canal. The professional ice hockey team, the Revierloewen, played from 1997 to 2007 before financial trouble forced a move to Gelsenkirchen. Oberhausen is a sports city in a way that does not show up on most lists of German sports cities.

The historical layers are visible if you know where to look. The Ruhrchemie synthetic oil plant at Holten was a target of the Allied oil campaign in 1945 - US forces reached it on 4 April that year. The mayors have alternated SPD and CDU through every decade since reunification, currently Thorsten Berg of the SPD, elected in 2025. The city sits on the river Emscher, which spent a century as an open industrial sewer and is now in the middle of one of the largest river-restoration projects in Europe. Twelve and a half percent of the population is non-German, the children and grandchildren of postwar guest workers from Turkey, Italy, Poland, and the former Yugoslavia. The question Oberhausen asks - what does a city become when the thing it was built for stops mattering - is one a lot of the world is going to have to answer in this century. The Ruhr is just running the experiment earlier.
