The next city we visited on our AmaWaterways Danube River cruise was Passau, Germany before venturing to Vilshofen, Regensburg, and our weeks stay in Prague, Czech Republic. Passau is a town located in Lower Bavaria, Germany. The town is actually on three rivers, the Danube, Inn, and Ilz. The rivers brought great economic wealth to the area making Passau, for centuries, a leading trading center for “White Gold”, Bohemian salt. St. Stephan’s Cathedral is the home of the largest pipe organ in Europe with 17,774 pipes and 233 registers. The old section of the town has a real medieval feel that is typical to many German towns along the Danube. Vilshofen, Germany, is a small Bavarian town with a long history from Roman times till now. In 1794 a great fire incinerated almost the entire old town area. The reconstruction of the old town was conducted by architect Franz Anton Glonner from Burghausen. Regensburg, Germany which is a Unesco World Heritage site on the Danube River in Bavaria. The town has distinctive Romanesque and Gothic architecture with the 11th to 13th century buildings to include the market, city hall, and cathedral. Regensburg is an example of a central-European city with a history as one of the centers of the Holy Roman Empire. Regensburg survived the destruction that periled other cities during WWII helping to preserve the beautiful architecture of the city. The buildings in Regensburg were mostly constructed of stone as opposed to wood. All restoration in the city is carefully monitored and has been legally protected since 1975 in accordance with the Bavarian Law for the Preservation of the buildings. We had a traditional sausage, sauerkraut, bread, and beer lunch at one of the oldest restaurants in the world, the famous Wurstkuche kitchen. It was originally built to feed the masons who built the Stone Bridge centuries ago. The Stone Bridge is a masterwork of medieval construction.
