Beginning in 982 the Sargans region was part of the lands of the Counts of Bregenz. In 1160, the male line of the Counts of Bregenz died out. Count palatine Hugo of Türbingen inherited most of their lands, through his wife Elisabeth. His son, Hugo, inherited the Bregenz lands around Lake Constance, including Sargans. This Hugo, who adopted the name Montfort und Werdenberg built or expanded Sargans Castle before his death in 1228. Excavations around the oldest part of the castle show that there was an earlier fort or castle, but nothing is known about that building. Hugo built the large bergfried, expanded the walls to the west and may have built a palas on that side of the castle.
In the mid-13th century the Montfort und Werdenberg lands were divided between Hugo of Werdenberg-Heiligenberg and his brother Hartmann of Werdenberg-Sargans. Hartmann took up residence in the castle and probably expanded the palas. The castle was first mentioned in 1282. Over the following century the wealth and lands of the Counts of Werdenberg-Sargans were divided over and over again between descendants. By the last 14th century, Count Johann I ruled over a small and poor county under the Habsburgs. In the Battle of Näfels in 1388, the count commanded a wing of the Austrian army that was supposed to cross the Kerenzerberg Pass. However, when he saw the threatened destruction of the main Austrian army, he fled back over the pass. The cost of the war, as well as other expenses forced Johann I to sell the castle and village to Leopold of Austria.
References: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.
