Grafenberg castle ruins, also known as the "Mörderburg"
The Grafenberg castle ruins, also known as “Mörderburg” or “Alt Schlössle”, are located on an elongated rock head above the road from Balzers to St. Luzisteig. It is located in the Fläscher municipality, but is owned by the municipality of Balzers.
A 25 meter long and 6 meter high wall has been preserved from the former castle complex. It was part of the east wall of a two-story palace building. Other visible remains of the wall indicate that the palace building had a base area of approx. 41 meters in length and 11 meters in width and that the castle complex once extended over the entire hill plateau.
No written sources have come down to us about the time of origin, builder and owner of Grafenberg. The type of masonry and individual finds point to the 13th century as the time of origin. Fire debris within the building indicates that the facility was a fire victim.
The castle complex was likely to have been in connection with a dam. This once extended from the foot of the castle rock to the flank of the opposite Guschnerberg and blocked off the valley at its narrowest point. Remnants of this dam are still present in a strip of forest below the castle rock.
In 2005 the ruin was secured, preserved and restored and archaeologically examined. The castle complex is under the protection of the Swiss Confederation and the Canton of Graubünden.
