Two of Europe's centres of culture and tourism, Vienna and Opatija, continue their long relationship based on a mutual historical, social and cultural heritage. This connectedness was the basis for Vienna Week, an event during which Opatija's cafés offer typical Viennese sweets such as the famous Sachertorte, and restaurants prepare culinary specialities to traditional recipes. Vienna Week also includes various musical and dance evenings, an exhibition of works by famous artists, children's workshops and round table discussions with renowned guests. The culmination of Vienna Week is the gala Viennese Ball in the Crystal Hall of the Hotel Kvarner, where numerous tourists and distinguished guests, ambassadors, mayors of twinned towns, as well as the political and economic elite from Vienna and people from the public life of Opatija, dance to the rhythm of the waltz.
