Vienna, the Austrian capital embraces all the traditions of a European city. Many buildings from Roman foundations through the Gothic, Baroque and Historicism times are still preserved here. Therefore Vienna is referred to by many as a unique union, with each of the urban layers surrounding the oldest historic centre being equally important to the overall flavour of the city.

Tourists are eager to visit Vienna because of the city´s exciting combination of the royal-imperial flair of the past with the latest trends, the responsible cultivation of a precious heritage and its charming traditions. Furthermore Vienna is often called “the capital of music” due to its musical legacy. Vienna is also regarded to be a place where the quality of living is one of the highest in the world. And last but not least Vienna is one of the most popular conference cities in the world.
