Hjularöd Castle was first mentioned in 1391, but the current castle was built in 1894-1897. It was built on command of the former owner, chamberlain Hans Gustaf Toll. French medieval castles, the château de Pierrefonds in particular, were inspiration for the castle when architects Isak Gustaf Clason and Lars Israel Wahlman designed it. Outside scenes from the television series Mysteriet på Greveholm (The mystery at Greveholm) in 1996 were filmed in the courtyard of the castle. The castle since 1926 is owned by the Bergengren family and is not open for the public.
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.
