The city of Vienna was essentially founded by the ancient Romans, who erected several military camps along the river Danube, which was then the border of their empire. One of them, called Vindobona, lies beneath the modern city center and you can actually visit Roman excavations today.

The city's importance grew rapidly with the rise of the Habsburg empire, who made it their residence in the late middle ages. In 1529 and 1683, Vienna was sieged by Ottoman armies, but they failed to conquer the city in both cases.

In the early 19th century, the Holy Roman Empire was dissolved and Vienna became the capital of the newly founded Austrian Empire (which later turned into the Austro-Hungarian Monarchy), still under the rule of the Habsburg dynasty. In the late 19th century, Vienna became a truly cosmopolitan city with a population exceeding 2 million - more than today. Impressive buildings were erected then, many of which can still be seen today.

Pride goes before a fall, and thus the first half of the 20th century was certainly not the best time in history: WW1, which brought the end of the monarchy, a considerable reduction in the size of Austria and a premature democracy, followed by fascism and WW2. After that, Vienna was somewhere between east and west for a few decades. Eventually, Austria has re-established her international reputation, and Vienna has regained the status of a cosmopolitan city in central Europe.

Even though nowadays Vienna is a modern city such as many others, you can still see and feel the heritage of the Habsburg monarchy in many places (which is, admittedly, often touristily exploited). But when you take a closer look aside of well-trodden visitor's paths, you can also spot the more recent history which sometimes appears to be closer to eastern Europe than the West.

Vienna has a long tradition of arts, and consequently a large number of museums. The collections on display range from traditional paintings to very specialized topics such as globes, schnapps or undertakers.

During their long reign, the Habsburg dynasty collected numerous works by artists such as Raphael, Caravaggio, Tizian, Rubens, Bruegel, Arcimboldo and many others. Those paintings, as well as artefacts from ancient civilizations, are on display in the Kunsthistorisches Museum. Speaking of Habsburg: The crown jewels of the Holy Roman Empire and the Austrian Empire as well as many other valuables can be seen in the Secular and Ecclesiastical Treasury.

Paintings of the 19th and early 20th centuries, most notably Klimt, Schiele and Kokoschka, are hosted in the Upper Belvedere. Similarly, the Leopold Museum is focused on paintings of the early 20th century. It is located in the so called Museumsquartier, a complex which houses several museums, but also bars and restaurants. An impressive collection of drawings (e.g. by Dürer) and prints can be found in the Albertina.

The history of Vienna is well represented in the Wien Museum, next to St. Charles's Church not far from the conference venue. MAK, the museum of applied arts, has a large collection of handicrafts from medieval to contemporary periods. The Sigmund Freud Museum is located in the former place where the inventor of psychoanalysis lived and worked. The rich Jewish history of Vienna is revealed in the Jewish Museum Vienna.

This is only a short list of the most prominent museums. If you want to go into more detail and maybe really want to visit the schnapps museum (yes, there is such a thing!), please refer to this comprehensive list of museums in Vienna.

Even though it is not exactly a museum, Vienna's central cemetary is certainly worth a visit. It is located half way towards the airport (S-Bahn station Zentralfriedhof) and has a (dead) population of  almost twice the present (alive) city of Vienna. Famous people are buried in the VIP section which has a Jugendstil church and graves for all the federal presidents of Austria since 1945 and most of the federal chancellors. Moreover, the VIP section covers the graves of Beethoven, Boltzmann, Brahms, Hansen, Hoffmann, Ligeti, Loos, Marcus, Salieri, Schmidt, Schönberg, Schubert, Strauss, Zawinul and many others. The cemetary also has jewish, buddhistic, protestant, islamic and orthodox sections.

Another cemetary of interest is in Sankt Marx. It was not used anymore after 1874 and preserved since then. Mozart was buried there, and a memorial can be visited, even though the exact location of his grave is unknown, because he was poor then and buried in an anonymous mass grave.

A Beislis a typical, small pub which serves traditional Viennese food at moderate prices, which does not mean it must be of poor quality. Such places can be found in many locations, and they often have a significant fraction of regular guests from the neighborhood.

If you want to try Viennese cuisine, probably the most famous dish is Wiener Schnitzel, originally a veal cutlet enveloped in crispy breadcrumbs, but nowadays mostly offered from pork or chicken (which are cheaper). Other typical foods are Tafelspitz, a delicately boiled cut of beef; Rostbraten, the Viennese equivalent of entrecôte and goulash, which the Viennese borrowed from Hungary (which was then part of the Habsburg empire). As you can already guess, vegetarianism wasn't invented in Vienna. Nonetheless, even people who don't eat meat can enjoy typical Viennese desserts: Kaiserschmarrn (follow the link for a description) or Palatschinken, thin pancakes filled with jam.

The Viennese Kaffeehaus (coffeehouse) is more than just a place where to have a quick coffee. In fact, it can be considered as a kind of public living room where one sits over a single cup of coffee for many hours, reading newspapers or books. There are many traditional coffehouses in the inner city, and already in the early 20th century, those were the focal points of intellectual life in the city. Peter Altenberg, a famous writer and poet of that time, named the Café Central when asked for his residence, and had his mail delivered there. It is located in the ground floor of Palais Ferstel, where we will have the Conference Dinner. Even today, Altenberg can still be seen sitting there - as a statue.

You will encounter many traditional coffeehouses when strolling through the city, and one can be found in proximity of the conference venue: Café Museum, which is located at the northwest corner of Karlsplatz. Its original interior decoration had been designed by Adolf Loos, but is unfortunately lost. Among many others, the painters Klimt, Kokoschka and Schiele were regulars there.

Even though you will most likely succeed ordering just "a coffee", Viennese tradition has developed a large variety of that drink, depending on how it is prepared. Don't worry if you can't keep terms like Mokka, Verlängerter, Melange, Einspänner, Kleiner Brauner apart - many Viennese people can't either. All of those are merely composed of five ingredients at most: coffee, water, milk, sugar and cream. A glass of plain water is always served with the coffee.

Typically, coffeehouses also offer a selection of food, snacks, and - most notably - various kinds of desserts. Pastries that go well with coffee are Apfelstrudel(filled with grated apples) or Topfenstrudel(filled with sweet cheese), the latter often being served with vanilla sauce.

Another typical institution in Vienna and surroundings is the Heuriger, a kind of tavern where wine-farmers sell their own products. The name Heuriger literally means "of this year" and tells they serve wine from the most recent harvest. Originally only beverages were sold and you had to bring your own food, but nowadays every Heuriger has a bar where you can fetch some typical farmer food.

A traditional Heuriger does not sell any alcohol which is not self-made; that also means they do not sell beer. However, there are some touristy places, which are rather a restaurant than a Heuriger - Grinzing is such an area which has more tourists than locals. More traditional (and also less expensive) Heurige can be found e.g. in Nussdorf (terminal station of the northbound D tram) or Neustift am Walde (Bus 35A has a stop by that name).
