Experience an open-air spectacle in one of the city's most famous squares. Vienna's Heumarkt is not only impressive due to its central location in the 1st district, but also because of its historical significance, lively gastronomy, and good connections to many of the city's sights, which make this square something very special. The interplay of old and modern architecture is particularly striking in the former Winter Palace of Prince Eugene, which now houses the House of Music.
