Schwörwochenende + Schwörmontag
The unofficial public holiday in Ulm. On the penultimate Monday in July, the traditional Schwörmontag takes place, on which the mayor promises to be a mean man to the citizens. Afterwards, the "Nabada" takes place in the double city, when thousands of inflatable boats sail down the Danube. The event concludes with a large festival on the cathedral square with the Schwörkonzert.
The Schwörwochenende celebrations precede Schwörmontag. On the Saturday before Schwörmontag, the Lichterserenade takes place, when the Danube is lit up by over 20,000 lights.
