Örbyhus estate existed already in the 14th century, but the first castle was built by John Kristiernsson (Vasa) around then year 1450. It was a strong fortification with tower. Örbyhus remained in a possession of royal Vasa family until the end of 16th century. Gustav Vasa, who acquired Örbyhus through an exchange with his cousins in 1548, constructed the national fortress in the middle of Uppland complete with ramparts, moats and 54-foot-high stone walls around his grandfather’s stronghold tower. In Gustav Vasa’s castle there are many hidden passages and casemates with space for a garrison and stores for many years. The former King Erik XIV was imprisoned in Örbyhus until his death 1574-1577.
Gustav Banér, the governor of Västergötland, acquired Örbyhus in 1641 and rebuild the castle in the present form of a baroque castle. Örbyhus was owned at the beginning of the 18th century by de Geer at Leufsta, who made both Leufsta and Örbyhus the entailed estate of his nephew, the scientist Charles de Geer. During the 200 years that followed it was the names of de Geer, von Platen, de la Gardie, Klingspor and Barnekow that left their mark on Örbyhus.
In 1900 the castle was purchased by Count Carl Gustav von Rosen; it was taken over during the same year by Count Eugène von Rosen, who commissioned extensive restoration and decoration work for the building.
Today guided tours are arranged during most of the summer season of King Erik XIV’s prison, the castle park and the carriage museum.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
