Linz is the third largest city in Austria with 205,000 inhabitants (2018), on the Danube ( Donau ) river, and the capital of the federal province of Upper Austria (Oberösterreich) and forms the heart of Austria's second strongest economic region. Linz is primarily known as a major industrial centre but also has a very picturesque historical old town including Austria's largest central square, surrounded by an impressive ensemble of Baroque architecture. Linz has tried to reposition itself as a cultural hub with numerous new museums and events. The tourist slogan of the city is "In Linz beginnt's" ("It starts in Linz").
