Graz is the capital city of Styria, a region in the southeast corner of Austria. It is located in between rolling hills, to the north, east and west, only open to the south. Graz is full of impressive architecture which mainly dates back to the time of the struggle between Reformists and the Habsburgs' Counter Reformation. Protestant buildings like the Landhaus and many different palaces encounter buildings like the old University, the Mausoleum and the Minoritenkirche, were erected to represent Graz's strict Catholic beliefs. The major example is without doubt the Schloss Eggenberg which represents Baroque architecture in Graz. The castle has a meaningful influence on the appearance of the city and houses the biggest collection of early modern weapons and suits of armour in Europe. A very significant landmark of the city is the romantic Uhrturm, a tower that still uses the original mechanism from 1712 and which is used as a traditional location for the first kiss of people. In the 19th century Graz became bigger in size and still today many buildings represent the growth and the development for example the Karl-Franzens-University, the City Hall and the opera house. Today Graz is the second largest city in Austria with a population of about 230.000 people. It offers a great deal of cultural opportunities, like the Styriade, an annual exhibition, dedicated to contemporary art, theatre and performance art.
