Under the motto "Cities for citizens" the Vienna days in Ljubljana took place. Vienna´s mayor Dr. Michael Ludwig opened the event together with the vice mayor of the city of Ljubljana Dejan Crnek at a concert with music of Slovenian and Viennese composers. The focus of the musical contribution was Ludwig van Beethoven whose 250^th birthday is celebrated by the City of Vienna beginning in December 2019 with the anniversary year "WienBeethoven2020".

The moderated stage-talk between Vienna´s mayor Michael Ludwig and Ljubljana´s mayor Zoran Janković about how both cities can offer their citizens as much quality of life as possible opened the two conference days in the Ljubljana Puppet Theatre. Afterwards the two mayors visited various projects in the centre of Ljubljana. During the sightseeing tour mayor Ludwig presented a public book case to the Slovenian mayor. The highlight of the Viennese mayor´s visit was his entry in the Golden Book of the City of Ljubljana.

On the two conference days, experts of both cities exchanged their experience and knowledge regarding recycling economy, overtourism, public space being the "living room" of the city, violence against women, care of the elderly and new technologies for elderly people, as well as measures against poverty and homelessness. Best practice examples from Ljubljana and Vienna were presented and current urban challenges of both cities were discussed.
