The Kunsthistorisches Museum in Vienna is one of the foremost museums in the world, with rich holdings comprising artworks from seven millennia – from Ancient Egypt to the late 18th century. The collections of Renaissance and Baroque art are of particular importance. The main building shown above houses the Picture Gallery, the Collection of Greek and Roman Antiquities, the Egyptian and Near Eastern Collection, the Coin Collection, and the Kunstkammer that reopened in March 2013. It was opened around 1891 at the same time as the Naturhistorisches Museum, by Emperor Franz Joseph I of Austria-Hungary. The two museums have identical exteriors and face each other across Maria-Theresien-Platz.
