Hofburg Palace (Winter Palace) - Ub Herngasse
This was the Imperial winter home of the Hapsburgs and allowed them to stay close to the political pulse of their empire until 1918. The origins were a mediaeval castle but it expanded along with the empire and each successive emperor. The complex includes the Spanish Riding school, home of the talented Lipizzaner horses, royal apartments, the Hof Kapelle where the Vienna Boys Choir perform and Treasury rooms with important exhibits from the Hapsburg's reign. Also home to the Austrian president's office. Opening hours for the Imperial Apartments Wed-Fri 10am-6pm (9pm Thu), entry €7.50
