Schloss Eberstein, Medieval castle in Eberstein, Austria.

Schloss Eberstein stands on a steep rock above the Görtschitztal valley in Carinthia. The lower castle, grouped around an inner courtyard, was rebuilt in historicist neo-Gothic forms in 1851 and 1868 under Count Alfred Christian Carl Christalnigg. It has stepped gables, crenellations and turret-like projections. The church of St. Georg, first documented in 1252, adjoins the south side.

The original Eberstein castle, first mentioned in 1078, stood higher on the mountain at Gutschen and was already described as ruined in the 17th century; its remains were lost to a dolomite quarry in the mid-20th century. The lower castle, today's Schloss Eberstein, was held by the Görzer ministerials in the 14th century, passed to Moritz Welzer in 1457, and was expanded by the Welzers in the second half of the 16th century. After the Protestant Welzers were forced to emigrate during the Counter-Reformation, the estate went to the Christalnigg counts in 1630, who rebuilt it in neo-Gothic Tudor style in 1851 and 1868 under Count Alfred Christian Carl Christalnigg.

The castle church of St. Georg on the south side was first documented in 1252 and long served as the parish church. Its 19th-century windows hold stained glass, and a wall fresco uncovered inside sets the New Testament against the Old, its German inscriptions pointing to the Reformation era. The gallery parapet is painted with busts of the apostles.

The castle stands on a steep rock above the Görtschitztal, and the site is reached on foot; the former upper fortress on the Gutschen heights was destroyed by the dolomite quarry, so only the lower castle remains. The chapel of St. Georg on the south side, first documented in 1252, holds a 19th-century altar with a central figure of St. George and an organ gallery painted with busts of the apostles.

The upper castle, first mentioned in 1078, was already described as ruined in the 17th century; its remains, still visible until the mid-20th century, were destroyed by a dolomite quarry. The name Eberstein passed to the lower castle and to the municipality.
