Passau and the Danube.
Introduction
Built at the confluence of the Danube with the Inn and Ilz, Passau is an alluring city of pastel painted façades.
Once the seat of the largest diocese of the Holy Roman Empire, the Oberhaus Citadel of the Prince-Bishops still looms over the city, while the Baroque cathedral owns the world's largest church organ with 17,774 pipes !
