Schloss Gundersdorf

Schloss Gundersdorf in Klagenfurt am Wörthersee, Austria, is a manorial residence whose origins lie in the medieval settlement of the region and whose appearance dates largely to an 18th-century rebuilding. The place is first recorded in 1245 under the older names Hundreinsdorf and Hundrensdorf in a donation deed associated with Duke Bernhard, and local tradition links the site to early-medieval edlinger farms (edlinger farm, an early-medieval rural holding). The building’s later conversion into a manor reflects the shift from small medieval farming units to a consolidated manorial estate by the modern period.

During the late medieval and early modern centuries the site functioned as an agricultural estate. Documentary references point to a working farm on the location by the 1500s, rather than a large fortified residence. In the mid-1700s the estate was enlarged and remodelled into a country manor by Anton von Dreer; the external form seen today largely stems from that mid-18th-century transformation and has changed little since.

Ownership of the property passed through several private hands in the 19th and 20th centuries. Josef Plasch acquired the estate in 1802, and it transferred to Jakob Ulbing in 1834. By the late 1800s Alfred von Offermann and Reinhold von Mohrenschildt were among the proprietors. Johann Tauschitz purchased the property in the early 20th century and his family retained it until 1964, when the Horner family became owners and carried out an interior restoration in 1973 to adapt rooms for guest accommodation. One account records continuous private ownership from 1912 and notes ongoing agricultural and commercial use.

The site also preserves a small late-18th-century chapel located to the north-east of the main house, which contains a life-size crucifix. The main building has been placed under state protection as a historic monument, listed under registration number 12513.
