Rosenmontag is the highest holiday in the Rhineland and of course also in Bonn. The "Zoch" with Prince Marco and Bonna Nadine starts at Thomas-Mann-Strasse and moves past the Minster and City Hall into the Old Town.
The Shrove Monday procession in Bonn in 2023 is under the session motto „Mit Pappnaas oder Höötche, mer sitze all in eenem Böötche“.
