With approximately 230.000 inhabitants, Graz is the 2nd largest city of Austria, situated in the region of Styria, 180 km (110 miles) south-west of Vienna. It has three universities (the University, the University of Technology, and the University of Music and Dramatic Arts), a pleasant old center that is not yet overcrowded by tourists, and nice hills and mountains nearby to the north, plus a wine growing area with rustic wineries to its south.

The Old Town of Graz is one of the best preserved in Europe and was awarded World Cultural Heritage by UNESCO in 1999. In 2003 Graz will be European Cultural Capital.

The airport of Graz can be reached via Vienna, Frankfurt, Zurich, ... and some other "hubs". By train, it takes 2 hours and 40 minutes from Vienna.
