16498 Passau           Discovered 1990 Sept. 22 by E. W. Elst at the European Southern Observatory.
The Bavarian city of Passau is at the confluence of the Danube, the Inn and the Ilz. Originally a Celtic settlement, and later a Roman camp, it was civilized by St. Boniface in 739 and made a city in 1225. St. Stephan's Cathedral houses the largest church organ in the world (17~774 pipes, 233 stops and 4 consoles).
