Vienna is always worth a visit!

Even if you hurry, it is nearly impossible to see all the sights of Vienna during one visit. Luckily a lot of them are close to Pension Dr. Geissler, like St. Stephen's Cathedral, Hofburg Palace, the Opera House – Staatsoper and the Capuchins' Crypt (Imperial Crypt). Before leaving, you should see at least a few of the following sights:

St. Stephens Cathedral
Hofburg
Spanish Ridingschool
Schönbrunn Palace
Opera house
Secession
Capucine's Crypt
Viennese Giant Ferris Wheel
Prater
Danube Tower
