Michael Häupl´s last trip abroad in his function of mayor of Vienna was to Prague on May 13th 2018. In the residency of the Austrian ambassador he opened the Vienna days together with the mayor of Prague Adriana Krnáčová.
In the following two days the exchange of experience of the decision-makers and experts was about urban planning, public space and modern communication in the city.
The Viennese "Heurige" (an Austrian establishment where wine from the latest harvest is served) that was organised at the Old Town Hall was open to the general public. The vineyard Cobenzl served traditional "Heurigen" delicacies and original wine from Vienna. Beneficiary of the proceeds was the charity organisation "Debra" which advocates for butterfly children.
