Vienna
The city of Vienna has long been a city of culture, and this is reflected within its plentiful tourist attractions and endless sightseeing opportunities. Tourists will find that the Vienna State Opera (Wiener Staatsoper) is one such example of Viennese culture at its very finest, along with many other attractions, such as the glorious University Botanical Gardens. The royal summer palace of the Schloss Schonbrunn is one of the most visited of all the tourist attractions in Vienna and this breathtaking building is simply enormous. You have to literally stand outside of the Schonbrunn Palace to fully appreciate the sheer scale of this colossal architecture, which actually comprises a staggering 1,440 different rooms and even features its very own zoo.
