Sverresborg Castle is named in honour of the rabble Sverre, who ruled in the 12th century. It was built in the ancient city of Trondheim on a well-located site: rather inaccessible and overlooking the surrounding countryside. The castle was completed in 1883.
King Sverre called Sverresborg - "Castle Zion", in honour of the fortress of the biblical King David's fortress. Here he established a residence for himself, from which he ruled and took important military affairs. In 1884, Sverre officially became King of Norway, defeating his rival's fleet in a sea battle.
In 1188, the castle was attacked and completely destroyed. According to written sources, Sverresborg was rebuilt 9 years later, but in the same year after a siege, the castle was again plundered. The last mention of Sverresborg date back to the reign of Sverre's grandson, when in 1263 he allowed the walls of the castle to be dismantled for building material due to the end of the civil war.
The ruins of the castle remained untouched until the Second World War, until German troops began using it as an outpost. The warfare caused irreparable damage to this historical monument. However, the town's residents cleared the area of unwanted stones by their own efforts and built a large open-air museum, which uses the picturesque ruins for research and education. Houses and outbuildings from many neighbourhoods were brought here. The reserve reflects ancestral traditions and almost completely reconstructs the old economy.
Thus, the once mighty Sverresborg Castle, which served as an impregnable fortress, has now become an impregnable fortress, is now a historical monument and protected as a Norwegian national treasure.
