The Habsburgs' collections, and the city where, around 1900, Klimt, Schiele and Loos tore it all up.
The Habsburg collections in a gilded palace, with the largest group of Bruegels anywhere. Klimt painted the spandrels above the staircase.
Prince Eugene's Baroque palaces, holding Klimt's The Kiss and the great Austrian collection.
The largest collection of Egon Schiele in the world, with Klimt, Kokoschka and the Wiener Werkstätte.
The artists' exhibition house of 1898 with its dome of gilded laurel leaves. In the basement, Klimt's Beethoven Frieze.
Rooms, ruins and curiosities: the city's other museum.
Anatomical wax models commissioned by Joseph II in Florence in the 1780s, in their original rosewood and Venetian glass cases.
One of Europe's largest cemeteries: Beethoven, Brahms, Schubert, and Adolf Loos's own cube of a gravestone.
An 1880 coffee house of billiard tables and worn banquettes, almost unchanged.
The sculptor Fritz Wotruba's church of 1976 is a pile of 152 concrete blocks, apparently stacked at random, with light coming in through the gaps.
Adolf Loos's tiny bar of 1908, about 27 square metres, with mirrors that make it look like a grand hall.
One of Vienna's six Second World War flak towers, built so thick it could not be demolished. It now holds an aquarium, with a climbing wall on the outside.
The abbey and its 12th-century Verdun Altar, 20 minutes away.
Kunsthistorisches Museum at opening → lunch in the museum café under the dome → the Secession → walk to the Belvedere for the end of the afternoon.
