Iberg Castle is located south-west of the town of Wattwil. The central keep is six stories tall and has an entrance on the north-west corner. The keep is surrounded by a curtain wall. The castle hill is protected by moats and some walls.
Iberg Castle was built in 1240 by Heinrich von Iberg who was a vassal of the Prince-Abbot of St. Gallen. The castle was briefly conquered in 1249 following the Toggenburg fratricide and again in 1290 during the rule of the anti-Abbot Konrad von Gundelfingen in St. Gallen. It was damaged during the Appenzell Wars in 1405 and soon thereafter rebuilt. During the conflicts leading to the Battles of Villmergen (from 1699-1712), the castle was besieged in 1710. After the Treaty of Baden in 1718 it was given back to the Abbot.
During the suppression of the monasteries in 1805, the castle became privately owned. Some of the housing was demolished in 1835, but the roof and battlements were rebuilt in 1902 and 1965 by the municipality.
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.
