Hompoš Castle, Medieval castle in Pivola, Slovenia.

Hompoš Castle is a long, two-storey building in Pivola near Maribor, partly built over cellars. Its core is the southern wing, still of stone with carved window frames and courtyard arcades, while the east and west wings are brick. After 1945, extensive rebuilding erased much of its historic appearance.

Hompoš Castle is first documented in 1323, when Reinprecht of Maribor granted his son Oton half of the upper castle with its tower, and gave the other half, with its chapel, to his wife Lucija and son Jurij. In 1348 the Walsee family acquired it through an exchange of estates; in 1352 it passed to Friderik Ptujski, whose family held it until dying out in the mid-15th century. The Stubenbergs inherited it and kept it until 1636.

The castle is also known as Pohorski dvor, and its German name was Haus am Bacher. Since 2008 it has housed the Faculty of Agriculture and Life Sciences of the University of Maribor and the University Agricultural Centre Meranovo–Pohorski dvor, so the former noble residence now serves as a teaching and research site.

The castle stands in Pivola, in the Municipality of Hoče-Slivnica just north of Maribor, not south of it. Since 2008 it has housed the Faculty of Agriculture and Life Sciences of the University of Maribor and the Meranovo-Pohorski dvor university agricultural centre, so the building is in academic use rather than open as a visitor attraction. The old castle park around it, with the longest tree-lined avenue in Slovenia, is partly preserved and protected together with the castle as a monument of local significance.

A lithograph by J.F. Kaiser from 1830 is the earliest known visual record of the fortress and shows the surrounding landscape as it appeared nearly 200 years ago. This historical image helps visitors understand how the castle and the land around it have changed over time.
