The first documented mention of the castle was as Regensburg property in 1327. In 1355, Leutold II of Kuenring, the first known owner, died. The Kuenringers were a significant Austrian noble family, named after their seat Kühnring. Leutold's successors, Andre of Lichtenstein and Friedrich of Wallsee, renounced ownership for money, and Eberhard I of Kapellen acquired it in 1359. Subsequent owners included Ernst Preuhofer, the Liechtensteins, Chunrad the Steward, the Öders, Reinprecht V of Walsee, the Hausers, and Christof Zeller of Riedau, who were known as robber barons.
Georg von Wolframsdorf inherited it and around 1530, it passed to the Tannberg family, who sold it to Hans von Tschernembl in 1575. His son, Baron Georg Erasmus von Tschernembl, expanded it in 1608 with Antonio Canevale's design. As a Protestant leader, Georg left the country, and the castle was confiscated in 1620, bought by Count Leonhard Helfried von Meggau. During the Upper Austrian Peasants' War in 1626, the castle was briefly occupied. Later, it belonged to the Starhembergers, Kuefsteiners, and Thurnheim Counts, until 1899, when Baroness Therese von Schwitter owned it. In 1911, Count Alexander Hoyos acquired it, and it remains with his family. Archduchess Alicia, the last Grand Duchess of Tuscany, died there in 1935. After WWII, the Soviets renovated the Chinese Salon.
The castle, located north of Schwertberg where the Aist river exits the Josefstal valley, appears fortified with a design from 1608. Surrounded by the Aist on three sides, it has a Renaissance garden, one of the few of its kind in Austria, and a sundial on a round tower. The main building, partly Gothic and partly Renaissance, features arcades, a falcon kennel, and a chapel dedicated to Saint Mary. The Chinese Salon has wall paintings and a small Rococo library.
The Beckov castle stands on a steep 50 m tall rock in the village Beckov. The dominance of the rock and impression of invincibility it gaves, challenged our ancestors to make use of these assets. The result is a remarkable harmony between the natural setting and architecture.
The castle first mentioned in 1200 was originally owned by the King and later, at the end of the 13th century it fell in hands of Matúš Èák. Its owners alternated - at the end of the 14th century the family of Stibor of Stiborice bought it.
The next owners, the Bánffys who adapted the Gothic castle to the Renaissance residence, improved its fortifications preventing the Turks from conquering it at the end of the 16th century. When Bánffys died out, the castle was owned by several noble families. It fell in decay after fire in 1729.
The history of the castle is the subject of different legends.
