Podvin Castle, Renaissance mansion in Mošnje, Slovenia

Podvin Castle (Grad Podvin, German Podwein) is a mansion in the village of Mošnje, south of Radovljica. It is a registered immobile cultural heritage of Slovenia. The building is now abandoned; it formerly housed a higher-category hotel.

Podvin Castle was first recorded in 1311 as "Trurn Podwein", held in hereditary possession by the Podvin lords, vassals of the Ortenburg counts. In 1399 Frederick of Ortenburg granted it as a fief to the Lambergs of Kamen Castle; after the Ortenburgs died out in 1418 it passed to the Counts of Celje, and in 1456 to the Habsburgs, who pledged and then sold it to the Wagen barons. Later owners were the Gallenfels, Mogajner and Mally families. In 1870 the French prince Camille de Polignac acquired the mansion as his family's summer residence; they left in 1939, and the estate was nationalized in 1946.

The castle is called Podvin after the Podvinski family, its first recorded owners, who held it as vassals of the Ortenburg counts from 1311. The last of the line, Sebald Podvinski, died in 1397 in a riding accident. Later owners included the Counts of Celje and the Habsburgs, and from 1870 the French prince Camille de Polignac, who used it as a summer residence.

Podvin Castle stands in the village of Mošnje, south of Radovljica. The building is abandoned and not regularly open, so arrange any visit in advance. It is a roadside village mansion rather than a hilltop site, reached by local road from Radovljica.

The castle's last private owner was Prince Camille de Polignac, who bought it in 1870 and used it as his family's summer residence until they left in 1939. His descendants did not seek its return after Slovenian independence and denationalization, so the mansion stayed in public use as a hospitality and tourist site.
