Vienna spent six hundred years being run from one set of buildings, and the Hofburg is the pile that grew around the job. This is the imperial quarter walked as a single morning: the squares, the courtyards, the horses, and the glasshouse where the walk ends with coffee.
Start on Heldenplatz, the grand unfinished square, and let the Neue Burg loom. Cut into the courtyards for the Spanische Hofreitschule — go at morning exercise, when the white Lipizzaner stallions work without the gala crowd. Through the Michaelertor dome onto Michaelerplatz, then back in to the Augustinerkirche, the Habsburgs' wedding church, where fifty silver urns hold their hearts.
You don't have to pay for the Albertina, though Dürer's hare is downstairs if you do; the terrace over the opera is free and gives you the Ring. Finish in the Burggarten — the Mozart statue on the lawn, the treble clef in flowers — and step into the Palmenhaus, the curved Jugendstil glasshouse, for breakfast among the palms. Karlsplatz is a short walk south when you're done.
