Fodor's Expert Review Mural Harbor

Just a 30-minute walk from the Old Town but a whole world away, Linz's old industrial Hafenviertel (Harbor Quarter) is now home to one of Europe's largest open-air graffiti galleries. Almost every inch of the area's old warehouses, containers, and other industrial facades have been taken over by colorful and evocative works by international street artists like Aryz, Lors, Nychos, and Roa, as well as local Austrian talent. There are about 300 artworks altogether, and you can see them all on a two-hour guided tour (€20), although this is currently only available in German. Alternatively, just stroll up and down Industriezeile yourself—many of the most impressive artworks are visible from the street.
