Considering the Hotel Spitzberg in Passau?
A VT member wrote the following comment about visiting Passau:
Veste Oberhaus - Oberhaus castle by globetrott
"Veste" Oberhaus is the old expression that is still officially used for the german word Festung (castle) in Passau. The castle dates back to the year 1219 and was the fortified residence of the prince-bishops of Passau.
Today it is a great place to have a perfect panorama-view on the city and inside you may find several museums and exhibitions about the history of Passau.
