From palaces to pastries.

In Vienna, the coffee house isn’t just a hangout — it’s an institution. According to UNESCO, lingering over a newspaper with a pastry and a strong espresso drink is officially a cornerstone of Viennese culture. Walk off your slice of Sachertorte with a self-guided tour of the city’s stunning traditional, Secessionist and modern architecture, such as the Imperial Palace, the State Opera House, the Kirche am Steinhof or the Kunsthistorisches Museum, an exercise in ornate geometry.
