The first known owner of Stora Väsby manor was Knut Karlsson (1485-1506). The Kurck noble family sold in to industrialist Emanuel de Geer in 1668. The present manor of Stora Väsby was completed around 1760 based on the design of Carl Hårleman. It is one of the best preserved Rococo-style buildings in Uppland.
Next to the castle is a Baroque-style park, which was built in the 1600s. The park was symmetric with hedgerows, trees and three ponds. Today Stora Väsby houses offices and residential apartments.
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.
