Gruber Palace

Gruber Palace sits on Astronomy Street above the Ljubljanica River and features elegant stone portals with a decorated facade showing intricate carved details. Inside, a distinctive oval staircase leads through multiple rooms now used for archival storage and document preservation.

Gabriel Gruber, a Jesuit architect from Vienna, built this palace between 1773 and 1781 as both his residence and a research institute focused on physics and hydraulics. After starting as a private home, the building was eventually adapted for public use and now serves as an archive.

The oval staircase displays an allegorical fresco from 1786 by Andrej Herrlein that shows trade, crafts, and technology in soft pastel tones. This painted wall reflects the interests of the scholars who lived and worked within these rooms.

The building is home to the Archives of the Republic of Slovenia, which preserves national documents and historical records on site. The location is easy to find by the river, though the interior is typically closed to casual visitors since it functions as a working archive.

The chapel within the palace contains grisaille frescoes by J. M. Kremser-Schmidt, an 18th-century artist, depicting scenes from the life of the Virgin Mary. This rare monochrome painting technique showcases the artistic ambitions invested in decorating this building.
