Schloss Ehrenhausen, Heritage castle in Ehrenhausen an der Weinstraße, Austria.

Schloss Ehrenhausen is a listed castle in the municipality of Ehrenhausen an der Weinstraße, in southern Styria, Austria. The complex features neo-Gothic architecture with worked stonework and several connected buildings set on a raised section of land.

Schloss Ehrenhausen was first documented on 27 August 1240, when Duke Frederick II confirmed a donation by Heinrich von Grafenstein to Seckau Abbey in "Ernhus". From 1543 to 1755 it belonged to the Eggenberg family, who had it rebuilt as a Renaissance castle and strengthened its fortifications against the Turkish threat. After the Ehrenhausen line died out in 1646 it passed to the Graz line; in 1904 it was bought by Theodor Kohn, former prince-archbishop of Olomouc, who lived there until 1915.

The name Ehrenhausen refers to an old lordship, and the castle still stands as a visible mark of that past in the village landscape. During events held on the grounds, wine culture and old architecture come together, giving this place a particular role in the South Styrian wine country.

The castle sits among vineyards and is surrounded by paths that are easy to explore on foot. The terrain is hilly, so sturdy footwear is a good idea if you plan to walk around the surrounding area.

The castle keep, a bergfried, dates from the 12th century and is the oldest part of the complex, predating the 1240 first mention in a charter of Duke Frederick II. The irregular three-storey four-wing building surrounds an arcaded courtyard. Theodor Kohn, retired prince-archbishop of Olomouc, lived here from 1904 until his death in 1915 and was buried in the neighbouring mausoleum.
