A free park festival lasting a day in July. It includes sport worshops, several stages with live music, sport performances, dance performances and much more.
Schloßberg
The castle perched upon a hill in the middle of the city around which Graz sprang up. The funicular (Schloßbergbahn) (10-day and tourist tram/bus ticket covers the ride), and elevator (Schloßberglift) (€2) will take the effort out of the walk to the top, although to use them would be to miss the wooded paths and some spectacular views. Alternatively, you can climb the 260 steps from Schloßbergplatz to the Graz clock tower.
Uhrturm
On the top of the Schloßberg, the symbol of Graz.
It comes to life with song and rotating dance figures every day at precisely 11:00, 15:00 and 18:00.
Schloss Eggenberg
Early Baroque architecture with lavish state rooms. There is a €2 fee for entering the park surrounding the castle, which they likely will not charge if you say you intend to take the castle tour. The castle guided tour is highly recommended though, as it contains dramatic wall and ceiling paintings, elaborate ceramic stoves, and inlaid wood floors. Eggenberg Castle is closed from 1 January till 23 March.
Graz's newest exhibition place. It's worth a visit, even if you only look at its design from the outside. It's right across the river from Hauptplatz at the Suedtirolerplatz. (You will definitely notice the blue bubble.)
It was built as a temporary project during 2003 for the Cultural Capital of Europe (Graz 2003) celebrations. People liked it enough so it stayed. Designed by the New York artist Vito Acconci, this accessible artificial island in the river, contains a stage for performances and a coffeehouse.
