I visited this WHS in July 2017 as part of a road trip from Vienna combining several stops along the Semmering Railway WHS.

I parked my rental car in the convenient Pfauengarten Underground Garage which is half way between the heart of the historic centre of Graz and the Schlossberg with the famous clock tower. I walked up to the Schlossberg first to take in the panoramic view of the historic centre of Graz from the colourful gardens and visit the landmark of the city of Graz - the clock tower (photo).

The panoramic view is not extraordinary with several modern and high rise buildings competing with the church spires and belfries. The clock tower was the highlight of my visit even though it really isn't that special compared to other clock towers in Europe. It is one of the oldest buildings in Graz and was mentioned in old documents as early as 1265. After 1560, the characteristic wooden gallery was added to the tower as well as a clock with clockworks dating from 1712.

After a while, I went down the 260 stairs from the clock tower and then I walked towards Hauptstrasse and the City Hall. A marble UNESCO inscription plaque can be found at the entrance to the city hall.

I also made an extra effort to visit the Eggenberg Castle and Gardens. The courtyard is worth visiting but again nothing special compared to other castles in Europe. Graz is a lively city but overall I failed to appreciate any OUV. Although close to Vienna, I'd very much recommend more time in Vienna or a trip to the Wachau Valley for the first time visitor in the area.
