Palais Khuenburg, 16th-century palace museum in Graz, Austria

The Palais Khuenburg stands in Sackstrasse between the Reinerhof, the oldest documented house in Graz, and the former Palais Herberstein. The U-shaped building with an interior courtyard extends across four floors and contains multiple exhibition spaces.

Maximilian von Schrattenbach, chamberlain to Archduke Karl and governor of Styria, built the house after 1564 on land belonging to Rein Abbey. In 1690 Count Gandolf von Khuenburg had it converted into an aristocratic palace. In 1738 it passed by exchange to Count Joseph Dismas von Dietrichstein, who raised the stables reaching to the Schloßberg rock. From 1876 to 1938 it served as a girls' secondary school.

The building now houses the Graz Museum, which presents permanent exhibitions about the city's history and organizes special thematic displays throughout the year.

The museum is located at Sackstrasse 18 and is accessible by public transportation connecting Graz's city center. Visitors should know that all four floors are reached on foot and contain different exhibition areas.

Archduke Franz Ferdinand, whose assassination triggered World War I, was born in this palace on December 18, 1863, while his parents stayed there temporarily. This birth connects the building to one of the most significant events of the 20th century.
