Passau.

A decorative map with bird's-eye view of Passau, by Georg Braun and Frans Hogenberg. TRANSLATION OF CARTOUCHE TEXT: "Patavia, Passavia or Patavium, formerly Boedurum, in German Passau, a flourishing city in Lower Bavaria; known for the confluence of the Danube, Inn and Ilz. With his most accurate drawing, the most reverend and illustrious Lord D. Urbanus of Passau, of the most noble and chivalrous Trenbach family, has contributed most graciously to the decoration, splendour and beauty of our geographical work. In the year 1576."
COMMENTARY BY BRAUN: "Passau lies on the eastern edge of Lower Bavaria, on the border with Austria, at the point where the Danube and the Inn flow together, almost as if on an island in an exceedingly pleasant and beautiful location.
It has become very powerful and wealthy due to its bishopric but also due to its merchants, who trade in various wares. For thanks to its fortunate location on the rivers it is very conveniently situated, and like Lyons in France and Ghent in Flanders has a favourable position for trade and lives in great prosperity."

This true-to-life view looks across the Inn to the city of Passau and beyond from the opposite hillside with the pilgrimage church of Mariahilf. The confluence of the Inn and Danube is clearly visible. On the peninsula-shaped Old Town between them, the mighty Gothic cathedral of St Stephen sits on a rise between the two rivers.
On the left bank of the Danube, 105m above the valley on top of St. Georgsberg, lies the fortress of Feste Oberhaus, with below it, on the spit of land between the Danube and the Ilz, the Feste Niederhaus. Passau became a diocese as early as AD 739 and was ruled by the prince-bishop from 1217 onwards.
