Veste Oberhaus, a former fortress, is called the Upper Castle. The fortress was built not only for protection from enemies. It also defended bishops from the citizens who strove for freedom. In 1822, the castle became a Bavarian Bastille and only in 1932 it became the city’s property. Now it houses a museum. You can get to Veste Oberhaus by bus and by car. However, most tourists prefer the Ludwig stairs, which consist of two hundred stair-steps carved out in the rock at the end of the XIX century.
The most interesting exhibits are about the salt trade (which was the most valuable product in the Middle Ages) and the history of crafts. 130 steps of the spiral staircase lead to the observation deck, which offers a singularly beautiful view of the city and the confluence of the three rivers.
