Did you know that Vienna's town hall was built using some 30 million bricks? You set the pace with your-well-informed guide as you tour some of the prime real estate in Vienna. Let your head spin as you scan the intricacies of St. Stephen's Cathedral, or step inside St. Peter's Church with its fantastic murals and domed gilded roof. In Vienna, the options come at you rapid-fire: Hofburg Palace, memorials to Strauss and Beethoven, the state opera house, and more. For the climax, use your skip-the line tickets and explore the UNESCO World Heritage site Schoenbrunn Palace and imagine riding Lipizzaner stallions among its hallowed gardens. You can extend your tour by 1 hour and add the nearby Belvedere Palace as well, housing one of Austria's most valuable art collections – with key works by Gustav Klimt, Egon Schiele and Oskar Kokoschka.
