Christiansfjel Fortress was initially established by Count Wedel-Jarlsberg in 1683 as Hammersberg Skanse. A tower with a cellar powder magazine was among the first buildings at this Norwegian fortress. During Christian V's 1685 visit to Norway he visited Hammersberg skanse on June 14th. Recognizing its important location on the Swedish border, he renamed the fortress Christiansfjell and directed continued improvements. An extensive report of the visit includes illustrations of the fortress at that time.
After the Great Northern War some of the smaller border forts were determined to be more expensive than their utility justified and they were closed. On July 13, 1742 Christiansfjell Fortress was closed and the materials were moved to Kongsvinger Fortress.
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.
