A visit to these marble halls, painstakingly decorated with frescoes and gold leaf, is an extraordinary experience. Between the KHM and its mirror the Natural History museum, a statue of Maria Theresia watches over the treasures within, mostly compiled by the Habsburgs as they added new territories to their empire. From a vast coin collection and unforgettable pieces of ancient Egyptian and Greek art, to rooms dedicated to great European masters, it's a treasure trove of art history. You'll find Roger van der Weyden's Crucifixion triptych, a Memling altarpiece, and Janvan Eyck's portrait of Cardinal Albergati. The picture gallery takes visitors through 16th- and 17th-century works by German, Dutch, Flemish, and Italian greats. Among them, Pieter Bruegel the Elder, Van Dyck, and Dürer. In March 2013, the Kunstkammer (Art Chamber) was reopened, displaying restored decadent treasures made for the splendor-addicted European royalty, including the famous Saliera of Cellini and 2,200 other unique objects. The new rooms have brought the museum more annual ticket sales than ever before.
