5 Sobieskiego Square in Tarnów, Aristocratic palace at Sobieskiego Square, Tarnów, Poland

The Sanguszko Palace at 5 Sobieskiego Square is a three-storey brick building on a sandstone base, its ground floor rusticated in darker grey. The ten-bay facade has three shallow projections; the central one rises to a triangular pediment with a round oculus, and a balcony with stone balusters sits above the entrance. The pitched roof is covered in reddish-brown tiles.

The palace was erected between 1785 and 1796 by magnate Hieronim Sanguszko. In the early 1800s, his son Prince Eustachy Sanguszko sold the building to Austrian administrative authorities, who used it as an official seat.

The building is called Dom Książęcy (Prince's House) after its first owner, Prince Hieronim Sanguszko, and later Budynek Starostwa for the Austrian and Polish district offices it housed. In 1846 starosta Józef Breinl received peasant leader Jakub Szela here and paid 4,000 złoty rhine dollars to peasants for loyalty to the Austrian emperor.

The building sits in a central location at Sobieskiego Square and is protected as a cultural monument of the region. Visitors can view it from outside and explore the square at any time of day.

In February 1846 starosta Józef Breinl von Wallerstern summoned village heads to the palace to oppose the Kraków uprising; during the Galician massacre about 150 victims were brought to the square beside it, and Breinl paid peasants 4,000 złoty reńskich for loyalty to the Austrian emperor.
