This lovely park lies on the slope where the Danube used to overflow into the Inner City before the construction of the Danube Canal. Many memorial statues stand in the park; the best known depicts Johann Strauss, Jr., composer of operettas and waltzes like "The Blue Danube Waltz." Here, too, are monuments to Franz Schubert and Hans Makart, a well-known artist whose work you'll see in churches and museums throughout Vienna. Verdant squares of grass, well-manicured flower gardens, and plenty of benches surround the monuments. The park is open 24 hours daily.
