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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
