To start your tour, you will explore the extensive grounds of the Veste Oberhaus, which is located high above Passau and is one of the largest and at the same time best-preserved castle complexes in Europe. Then head inside the more than 800-year-old castle walls, where history comes alive in a unique way. Walk in the footsteps of the Passau prince bishops, who once resided in the rooms in which today the Oberhaus Museum presents exciting exhibitions from the Middle Ages to recent history. An absolute highlight is the visit to the newly opened observation tower with multimedia presentation on the multifaceted history of the castles and palaces in the Inn-Salzach-Dona region. A spectacular panoramic view of Passau and the surrounding area awaits you on the top platform. The new Veste Oberhaus app accompanies you on a virtual adventure tour "in the footsteps of knights and prince bishops" through the castle complex. For example, the former drawbridge comes back to life, a panoramic tour shows the most beautiful vantage points and the treasure hunt invites you to discover objects from ancient times at authentic sites. Finally, a visit to the Batterie Linde lookout point is recommended, from where you can enjoy the most beautiful view of the picturesque old town and the famous confluence of the Danube, Inn, and Ilz rivers.
