With around 65,000 drawings and more than a million old master prints, the Albertina is a mightily impressive collection of art. Located in the largest Habsburg residential palace, the collection also includes more modern works - including two significant collections of Impressionist and early 20th-century art, and temporary exhibitions. Also on display are 21 exquisite Habsburg state rooms, spread over two floors of the palace.
Vienna’s Stephansdom (also known as St. Stephen's Cathedral) is kind of a big deal. As the national emblem of Austria, it attracts over 1 million visitors every year. And rightfully so – at over 800 years old, it’s home to some of the country’s most interesting historical and architectural sights.
The High Altar, which took seven years to build in the 17th century, is just one of 18 altars inside the impressive Gothic and Romanesque structure.

If your tastes extend to the more macabre, visit the catacombs, built during the 1735 Bubonic plague they're, erm, 'home' to over 11,000 skeletons.
The Belvedere is a World Heritage Site, a Baroque jewel and the site of the Austrian State Treaty. One of the oldest museums in the world and at the same time a venue for contemporary art.
The unique overall ensemble with the two palaces Upper and Lower Belvedere and the extensive garden is one of the most beautiful baroque buildings in the world.

After Empresses Maria Theresia purchased the palace, it was immediately dedicated to showcase the extended imperial art collection.
The strange cuboid building in Vienna's fashionable Museumsquartier contains the most-visited museum in the city. The Leopold Museum has a remarkable collection of Viennese Art Nouveau, the Vienna Workshop, and of the Expressionist period. It also has the largest Egon Schiele collection in the world - plus masterpieces by Gustav Klimt.
There are also revolving exhibitions and a great shop and cafe (with a great view overlooking the Museumsquartier).
In the oldest part of the Hofburg Imperial Palace you'll find perhaps the greatest treasury in the world.

In fact, the actual Imperial Crown of the Holy Roman Empire rests here.
In addition to the worldly mementos of kings, queens, and emperors, there's also an ecclesiastical collection which features relics ascribed to various saints.
