Directions (Qs. 13-16)

Vienna is a city of exceptional beauty, but it's not something that happened overnight. Its architectural legacy is mostly the result of its former role as the Habsburg capital of an Austro-Hungarian empire once eight time the size of today’s Austria. This influence isn’t just found in the city’s building however: besides the grand imperial palaces and churches created during 640 years of Habsburg rule, the city’s abundant green spaces were also often royal in origin. The famous Prater was an imperial game reserve until Emperor Joseph II gave it to the people as a park in 1766. There is also the influence of pre-first World War Vienna Secession on the city. Some buildings and paintings by the famous people helped Vienna’s place as the cultural capital of central Europe in the early 20th Century.

Vienna’s cultural reputation continues to this day with its 160 museums, four opera houses and over 15,000 concerts a year. Many composers have made it their home. It is a relaxed city: Brahms once said that he lived in Vienna “because I can only work in a village. The relaxed café culture for which Vienna is well known wasn’t based on Viennese gregariousness. It developed partly because the population density in the walled city encouraged the use of cafes as living rooms. The city anticipated today’s internet cafes, and teenagers could be seen to linger over a single coffee doing their homework in peace. The café culture has evolved and it can be found at Café Supersense on Praterstrasse. This is an unusual mix with plenty of vinyl, analogue cameras, a recording studio and even printing press all found within a beautiful 19th-century ‘palace’.

Surrounding the city’s walkable Habsburg core is the bourgeois Ringstrasse, a ring road dotted with mansions and public buildings. It was built on the site of the city’s razed defensive walls and bastions, which were demolished following an order by Emperor Franz Joseph I in 1857. Late February is a good time to visit the city, with Restaurant Week (22-28 Feb) in full swing. Vienna’s chefs understood the term ‘fusion’ long before it came into fashion, utilizing elements from many national traditions. However, while many dishes come braised, boiled or stewed, a golden, pan-fried coating of flour, egg and breadcrumbs is still the preferred way to cook almost anything – and locals wouldn’t have it any other way.
