Story:
The place was first mentioned around 1074 by the Hochfrei Adalbert von Kilb. In the 12th century, the rule came to Rudolf von Perg. Friedrich von Perg was inherited by the Babenberg Duke Leopold V in 1191. In the 13th century, a knightly family again named itself after Kilb. In 1410 a knight from “Sebeck” was named as the owner. In 1460, Jörg von Pottendorf sold his castle in Kilb to Bernhard von Tiernstein, who built an extensive new building and, ten years later, bequeathed it to the brothers Rüdiger and Jörg von Starhemberg, but also promised the defense construction to his grandson Georg von Velderndorf. The latter probably received it, because in 1521 Hans Velderndorfer sold the fortress to Göttweig Abbey.
The castle was now called Grünbühel. He bought it back in 1534, but finally sold it to Jakob Gienger in 1549. Jacob's son Nikolaus had the old fortified building converted into a more comfortable Renaissance castle. As a result, the owners usually changed quite quickly. Around the middle of the 17th century, the Barons Ruess von Ruessenstein came into possession of the castle. Only the barons and later Counts of Wickenburg owned Grünbühel for a longer period from 1720 onwards. In 1830, Karl Theodor Graf Wickenburg had major construction work carried out, which gave the building its current appearance. In 1845 the castle came into rapidly changing bourgeois ownership. From 1969 to 2004 it belonged to the Friedel-Klarenberg family. Since then, Dr. Georg Graf Pachta-Reyhofen, lord of the castle at Grünbühel.
