Of all Vienna’s museums, the Kunsthistorisches Museum on Burgring still outshines them all (June–Aug daily 10am–6pm, Thurs till 9pm; Sept–May Tues–Sun 10am–6pm, Thurs till 9pm; €15). It’s one of the world’s greatest collections of Old Masters – comparable with the Hermitage or Louvre. Highlight is an unrivalled collection of sixteenth-century paintings by Brueghel the Elder, while the Peter Paul Rubens collection is also very strong and works by Vermeer and Caravaggio are worth seeking out. A number of Greek and Roman antiquities add breadth and variety. Set aside several hours at least: there is also an excellent café.
