The Kunstkammer at the Kunsthistorisches Museum is one of the most significant collections of its kind worldwide and encompasses the period of history from the late Middle Ages to the Baroque era. The members of the Habsburg family collected many fascinating objects made of gold, silver, ivory, and other rare materials including precious stones, ostrich eggs, corals, and shark teeth – around 2,200 of these wonders are on display in the Kunstkammer. The highlights of the exhibition include Salt Cellar by Benvenuto Cellini in addition to feats of technical genius such as automata, watches, and scientific instruments.
