Isenburg Castle was built by the Counts of Isenburg around 1100 if not prior. Occupied by several branches of the Isenburg family, it was inhabited into the early 17th century. Shortly after being abandoned, it became a ruin. After the branch of Lower Isenburg had extinguished in 1664 with count Ernst of Isenburg-Grenzau, the county was partitioned between the counts of Walderdorff and the counts of Wied-Neuwied. The present owner of the castle is Maximilian, 9th Prince of Wied, son of Carl, 8th Prince of Wied and Princess Isabelle of Isenburg.
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.
