Hässelby Castle (Hässelby slott) was built first in the 1640s by the riksråd Karl Bonde, who owned it until his death 1652. The original architect was Simon de la Vallée and the castle was finished about the 1660s by his son Jean de la Vallée, when Karl's son Gustaf Bonde owned it. The Bonde noble family owned the castle until 1931, when Stockholms stad bought it until 2010. Since 2010 SIVAB own the castle. Today Hässelby is opened for weddings, parties and conferences.
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.
