Graz is the capital city of Styria in Austria and the second-largest city in Austria (around 285.000 inhabitants) and an important university city. Graz's "Old Town" is one of the best-preserved city centers in Central Europe, for this in 1999 the historic centre was added to the UNESCO list of World Cultural Heritage Sites. Graz is a particularly fine example of a central European urban complex which experienced many centuries of Habsburg rule. The old city is a harmonious blend of the architectural styles and artistic movements that have succeeded each other since the Middle Ages, together with cultural influences from the neighbouring regions. For centuries now the original town centre, nestled at the foot of the Schlossberg with its famous Clock Tower, has been a repository of the architectural styles of each era, from Gothic, Renaissance and baroque to historical eclecticism and Jugendstil.
