Living close to a river, particularly a river in a narrow valley, probably means you have to accept that every now and again the waters rise. This water line is from 1824 when the Neckar overflowed its banks.
To put this in perspective: The square where the house with this mark stands is 100m away from river, and adding a bit more perspective:
The water level marked on an old house from a flooding in 1875.
A mural created by a school class in 2015.
A keystone with the year 1743 marked out.
The (most likely) dates of birth and death of Johannes Bückler, better known as Schinderhannes, painted on a house in the area where he used to live as an outlaw and robber. There are many legends (and five movies) about the man, making him into a more modern German version of Robin Hood which are in all probability not true.
