One of the Habsburgs’ most dazzling Rinsgstrasse palaces, the Kunsthistorisches Museum Vienna, houses the imperial art collection. It’s packed with priceless works by Old Masters, and treasures including one of the world’s richest coin collections. Behind the Hofburg, the former imperial stables have been transformed into the innovative MuseumsQuartier, with a diverse ensemble of museums, showcasing 19th- and 20th-century Austrian art at the Leopold Museum to often-shocking avant-garde works at the contemporary MUMOK.
