As the name of this event indicates, each autumn, the mayor of Jablonec nad Nisou surrenders rule over the town to musicians, dancers, conjurers and marketeers for one weekend. Gaiety and happiness sets in. The Lower Square is filled with stalls selling traditional artifacts, stalls with crafts, roasted piglets, beer and mead. Local as well as hosted artists perform here, shows, competitions and programmes for children are also prepared. The Festivities of Jablonec are usually held at the end of September.
