Vienna Days starting in Ljubljana
The programme includes a classical music concert, the making of the world's largest Sacher Cake and tours of Ljubljana revealing Vienna's influence on the Slovenian capital.
The Vienna days are the fruit of a cooperation agreement revived last year by the two cities' mayors and are organised by Eurocomm-PR, which represents Vienna in Ljubljana.
Honoured first will be the Austrian capital's classical music heritage, as the RTV Slovenia Symphony Orchestra, accompanied by Vienna solo violinist Lidia Baich and viola maestro Christian Frohn, will perform tonight works by Mahler, Mozart and Strauss.
Vienna and Ljubljana will justify their European Green Capital status with several presentations on Tuesday.
The Austrians will talk about their largest community-owned power plant and the city's intelligent transport system, while speakers from Ljubljana will focus on the Zero Waste Plan for the period until 2035.
A business forum entitled Cities of the Future - Vienna and Ljubljana will be held on Wednesday to provide insight into Vienna's strategy supporting innovation, start-up companies and the hosting of foreign companies and organisations.
The cherry on the Vienna Days cake will come on Wednesday afternoon at the Triple Bridge, where Sacher pastry chefs will make the biggest original Sachertorte in the world.
The rough recipe for a version of the famous cake measuring 3.5 metres in diameter is 2,000 eggs, 50 kilos of flour and butter, 40 kilos of sugar, 45 kilos of different types of chocolate, 80 kilos of apricot jam, 200 kilos of icing and 300 litres of sweet cream.
The detailed recipe for the Sachertorte, invented in 1832 by sixteen-year-old chef apprentice Franz Sacher at the behest of Prince Wenzel von Metternich, has meanwhile remained a well-kept secret, presently apparently only known to Sacher's head pastry chef and two senior assistants.
Moreover, organised twice each day as part of Vienna Days will be free city tours in three languages, which will highlight the traces of Vienna's influence in Ljubljana.
