Kasteel Radboud is one of a number of castles in North Holland, the building was commissioned by Floris V. The exact date of building is not known but the castle was completed before the St. Lucia's Flood of 13 December 1287. On 24 June 1517 the castle saved some of the Medemblik townsfolk from the raids of Grutte Pier and his Arumer Zwarte Hoop (band of marauding pirates).
On 12 August 1588 the castle surrendered to Diederik Sonoy and the Geuzen. The defensive function of the castle was reduced with the building of walls around the city of Medemblik in 1572 and due to both dismantling and lack of maintenance there was attrition of the castle buildings.
In 1889 the control of the property was returned to the state. Restorations were done by the State architect J. van Lokhorst with advice from R.J.H. Cuypers and the castle was used for the district court of justice until 1934. In 1931 a cannery near the castle burnt down exposing the foundations of a tower on the north west of the site and during 1936 the castle-moat was dug again.
From 1964 to 1965 further restorations were done with a more historical and architectural correctness and some of the previous renovations were removed.
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.
