Vienna has a long memory. Once the capital of the Habsburg Empire, the city still carries signs of its imperial past in its palaces, concert halls, and wide boulevards. Visitors can walk through the Hofburg complex, where emperors once ruled, or tour the opulent rooms of Schönbrunn Palace, which features 1,441 rooms and a maze in its gardens. But Vienna’s many historic buildings now house contemporary art museums, cafés, and institutions that reflect the city’s modern identity.
