City of Graz Historic Centre and Schloss Eggenberg

A blue alien watches the clock tower, on purpose

The single strangest building most Graz guides ignore is the Kunsthaus, a bulbous, iridescent blue structure locals nicknamed the Friendly Alien when it opened in 2003 for Graz’s year as European Capital of Culture. Its skin is made of acrylic panels that double as photovoltaic surfaces, and the design, by architects Peter Cook and Colin Fournier, includes sixteen roof nozzles that function as skylights, fifteen facing north for even studio lighting and one deliberately angled to frame a view of the Uhrturm, the medieval clock tower on the hill above. That is not a coincidence: the architects built a literal sightline connecting Graz’s newest architectural statement to its oldest, turning the historic tower into an exhibit inside the museum itself. If your itinerary is all Baroque palaces and Renaissance courtyards, spend an hour at the Kunsthaus for contrast. It sits right in the historic centre, on the Mur riverbank, and it is arguably the most talked-about building in the city among architecture circles internationally, despite older guides to the UNESCO site barely mentioning it.

The clock tower survived only because locals paid a ransom

The Uhrturm on the Schlossberg is one of the last remnants of the fortress that once dominated the hill, most of which Napoleon’s forces demolished in the early 19th century. Local citizens are credited with paying a ransom specifically to save the clock tower and a handful of other structures from total demolition, which is why this one landmark still stands watch over a hill otherwise stripped of its medieval fortifications. You can walk up via around 260 steps, or take the Schlossbergbahn funicular, which has run since 1894 and covers the climb in about ninety seconds inside glass panoramic cabins, giving you a sweeping view over the UNESCO-protected old town’s rooftops on the way up.

Straightening out the Landhaus and the Natural History Museum

The Landhaus, seat of the Styrian Estates since the 16th century, is a genuinely important Northern Italian Renaissance building with an arcaded courtyard attributed to the architect Domenico dell’Aglio, and it deserves its place on any heritage walk through the historic centre. But the Museum of Natural History Styria is not housed inside the Landhaus, nor is it primarily located within Schloss Eggenberg as some accounts suggest. It sits in the Joanneumsviertel, a separate museum quarter that forms part of the wider Universalmuseum Joanneum network, itself the oldest museum in Austria and one of the largest general museums in central Europe, spread across a dozen sites in Graz and beyond. Getting this straight matters if you’re trying to plan a museum day around opening hours and locations rather than assuming everything sits under one roof.

Eggenberg’s state rooms require a guided tour, and a seasonal calendar

Built in the 17th century as a summer residence for Prince Hans Ulrich von Eggenberg, the palace’s showpiece interior, including the extraordinary Planetary Room with astronomical ceiling paintings begun in 1678, is only accessible via guided tour, not free wandering. As of the 2026 season, the state rooms and the palace’s Alte Galerie, archaeology museum, and coin cabinet run from late March through the end of October, Tuesday to Sunday, with guided tours typically departing at 11am, noon, 2pm, and 4pm. Outside that window the interior closes for the season even though the gardens and grounds often remain accessible. If a Graz trip lands in winter, check the current schedule before building a day around Eggenberg specifically, since the palace’s most famous rooms simply are not open the way they are in summer.

What’s actually worth prioritizing

Graz has carried UNESCO City of Design status since 2011, part of the UNESCO Creative Cities Network, a designation that shows up less in any single building and more in how design runs through the city’s public spaces, from the Murinsel’s suspended shell-shaped platform in the river to the way the historic centre blends medieval, Renaissance, and Baroque layers without any single period dominating. Given a limited day, prioritize a walk through the old town’s arcaded courtyards, the climb or funicular ride up to the Uhrturm, and either the Kunsthaus or Eggenberg rather than trying to squeeze in both palace and gallery circuits on museum-heavy itineraries; Graz rewards slower wandering more than checklist sightseeing.

Practical notes

The Graz City Card covers free entry to numerous museums plus discounted public transit, and it earns its cost quickly if you’re visiting more than two paid sites in a day. The historic centre is compact enough to cover on foot or by bike, and the tram network’s six lines fill in anything beyond comfortable walking distance. Visit April through October for the most reliable weather and for Eggenberg’s interior to actually be open; expect larger crowds in peak summer months. For food, look past the generic strudel offerings toward Styrian pumpkin seed oil drizzled over a salad and a glass of Schilcher, a rosé produced almost exclusively in this region and rarely found much beyond it, at a traditional Gasthaus in the old town rather than a tourist-facing café on the main square.
