I agree here with Clyde. Throughout the 10h that I spent in graz I failed to see the sketchy ouv the site presents: "Historic Centre and Schloss Eggenberg reflects artistic and architectural movements originating from the Germanic region, the Balkans and the Mediterranean"

The city is nice enough with an abundance of Renaissance buildings and a nice cathedral with the rather surprising mausoleum of Ferdinand II. Apart from that the most satisfying part of the day was climbing the hill up to the clock tower.

Overall I would say that graz is a very pretty but rather unremarkable city. And unfortunately the list has plenty of these. I simply fail to see what exactly is graz supposed to bring to the table. As hard as I tried it just looked like yet another pretty central european city. I didn't see anything particularly outstanding about it.
