Palais Herberstein , Graz, Baroque palace museum in Sackstraße, Austria.

Palais Herberstein on Sackstraße is a Baroque palace with three stories and two courtyards that give the building its structure. A grand staircase with sandstone sculptures and painted ceiling frescoes forms the centerpiece of the interior.

The building arose in 1528 from the merger of two separate houses and later passed to the Herberstein family. They acquired it in 1742 through inheritance from the Eggenberg dynasty and shaped its development from that point forward.

The name recalls the Herberstein family, who inherited the palace in 1742 after the male line of the Eggenbergs died out. Count Johann Leopold von Herberstein commissioned Josef Hueber to rebuild it in Late Baroque style, with Rococo stucco and stoves by Heinrich Formentini. The second-floor Nobletage keeps a white-and-gold Spiegelsaal and Yellow and Red Salons named for their wallpaper.

The entrance is at Sackstraße 16, between the Kellersperg town house and Palais Khuenburg. The ground floor was heavily altered by inserted shops, so the historic rooms begin above street level. The two courtyards reach back to the Schloßberg rock, where niches cut into the stone once served as horse stables.

Craftsman Heinrich Formentini created the intricate Rococo stucco work and decorative stoves that visitors can still admire today. These details demonstrate the high level of craftsmanship that was once demanded in such a residence.
