There are no surviving records indicating when or how this castle was built. From the style of construction it appears to have been built in the 13th century and was in operation until the 15th century. By the 14th century the Counts of Kropfenstein begin to appear in historical records. They appear to have adopted the castle's name when they took up residence there. In addition to the area around the castle, the Counts had close relations with the Herrschaft of Rhäzüns. The Kropfenstein line died out in the 15th century and the castle began to fall into disrepair.[1]
