Hovgården is an archaeological site on the Lake Mälaren island of Adelsö. During the Viking Age, the centre of the prospering Mälaren Valley was the settlement Birka, founded in the mid-8th century and abandoned in the late 10th century and located on the island Björkö just south of Adelsö. Hovgården is believed to have been the site from where kings and chieftains ruled the area. Hovgården, together with Birka became a UNESCO World Heritage Site in 1993.
The oldest archaeological remains on Adelsö, found north of Hovgården, are grave fields and burial mounds from the Bronze Age (c. 1800-500 BCE). Apparently this culture survived into the Iron Age (500-800 CE) as graves from the early part of this period have been found at several locations in the area. At Hovgården some 124 graves have been found; the oldest from late Roman Iron Age (1-400 CE) and the youngest from the beginning of the Middle Ages (c. 1050-1520), indicating the area has been settled uninterruptedly throughout this period.
Just north of the parish church are five large burial mounds of which three are called Kungshögar. In Swedish, Kung meaning King and högar, from the Old Norse word haugr, meaning mound or barrow. Hovgården apparently was the location for a royal estate Kungsgård as early as the Viking Age (c. 800-1050 CE). An excavation of one of these royal mounds in 1917 revealed the remains of a wealthy man who lived around 900 CE. He was burned lying in a boat, dressed in expensive clothing but without weapons, accompanied by horses, cows, and dogs.
Birka, the oldest town in Sweden, was an international trade post. It has been assumed the royal settlement at Hovgården was established as the king's mean of controlling Birka. However, while Birka was abandoned in the mid-10th century, the royal estate was apparently not as the runestone U 11 from around 1070 which claims to have been carved for the king was erected next to the royal mounds. It was part of Uppsala öd, a network of royal estates supporting the Kings of Sweden.
Furthermore, King Magnus Barnlock had the old castle replaced by a palace built in brick, Alsnö hus, in the 1270s. In the palace, the king established the Swedish nobility through the Ordinance of Alsnö (Alsnö stadga) in 1279. However, the palace was destroyed before the end of that century, and as it was left to decay Hovgården lost in importance.
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.
