Korbisch Manor

In Treis-Karden, Rhineland-Palatinate, stands Haus Korbisch, a late Romanesque manor house and estate. It is considered the oldest continuously inhabited private building in Germany with its preserved appearance from the early 13th century.
History+
The origins of Haus Korbisch date back to the Ottonian period. Archaeological investigations around 1996 dated parts of the masonry to approximately 941 AD, with plastered walls and fresco fragments already existing then. The building acquired its current late Romanesque appearance around 1208 through renovations. It is believed to have served at times as the residence and official seat of the Archdeacon of Karden, who played an important role in the Archdiocese of Trier. After the collegiate church of Karden was dissolved in 1802, the house was privatized and served, among other things, as a wine press house.
