On the very border of Austria and Germany there is a small Bavarian city of Passau, located on the banks of the Danube, Inn and Ilz rivers, for which the city received the name "Dreifl? ssestadt - "city of three rivers". All three rivers have different water colors - Blue Danube, Green Inn and Black Ilz. They say that rivers merge almost at one point and even flow for some time without mixing. And the city of Passau is also called the "floating city" and the "Bavarian Venice". Every year on the last weekend of April, Passau hosts a folklore festival in which people from different parts of Germany and even from other European countries take part.→
