Vienna, Austria has it all. As the largest city in Austria and the nation’s capital, Vienna is Austria’s political, cultural and economic center and has a fascinating history that goes as far back as its founding in 500 BC by the Celts and its position of great significance in the Roman Empire in 15 BC. As a city famous for its musical tradition, Vienna was once home to Mozart, Beethoven, Brahms and Strauss and currently holds concerts and performances at a number of opera houses and the famous Wiener Musikverein concert hall. The diversity of architectural styles spans from Romanesque to Art Noveau and the relatively low buildings, imperial squares and abundance of green spaces keep Vienna’s urban expanses beautiful.
