The Danube floods every now and again, and in the town of Passau it's traditional for buildings to mark the heights of past floods. The most comprehensive set of markers was this one on the town hall. The highest flood was in 1501, but very close behind was an enormous flood just a decade ago in 2013. It inundated every building in town up to the second floor, and higher than that in some areas. Bring your galoshes.

Galoshes????

absolutely beautiful town and the most beautiful church I've ever been to, and I have been to a lot.

Did the trip the other direction a few years ago and Melk Abbey is really something to see.

If it were me, there would only be one mark representing the year I decided to get the hell out of a flood plain. This must be the south Florida of Europe.
