Explore the Italianate-style streets of Passau, where three European rivers have converged to shape a distinctive city. Meet your local guide and begin your walking tour through delightful old-world streets, taking in a pastel rainbow of building facades as you stroll. You will see the impressive Bishops’ Residenz from which powerful prince-bishops ruled secular and religious life for hundreds of years. Continue past the 14th-century Rathaus, or Town Hall, built on the site of a former fish market on the Danube. Conclude your walk at the magnificent 17th-century St. Stephen’s Cathedral. This baroque wonder houses Europe’s largest pipe organ, with more than 17,000 pipes, and inspired Franz Liszt to write his Hungarian Coronation Mass. Enjoy free time to explore more of the city on your own before returning to your awaiting ship.
