Schloss Schönbrunn
Inscribed on the UNESCO World Heritage List in 1996. It is the ultimate palace experience in Vienna, because the Habsburg summer palace can be found here. It is comparable in grandeur to Versailles and is definitely a must-see in Vienna. The palace has seen its fair share of excitement over the years, including a meeting between John F. Kennedy and Nikita Khruschchev at the height of the cold war. There are two possible tours available, the Imperial Tour showing 22 rooms and the Grand Tour showing 40 rooms. The shorter tour takes you into the west wing including the apartments of Emperor Franz Joseph and Empress Elisabeth (Sisi), as well as the imposing state rooms in the central wing. With the Grand Tour you can also visit the 18th-century rooms from the time of Maria Theresa. No photos, video taping, or backpacks allowed inside. The palace is wheelchair-accessible.; If you visit during late November to late December, or during Easter, then there will be a Christmas/Easter market open, where you can buy small gifts.
Tiergarten Schönbrunn
The oldest zoo in the world, built for Maria Theresa's husband in 1752. A map of the zoo is available here.
