Geography of Stockholm County

Birka (Birca in medieval sources), on the island of Björkö (lit. "Birch Island") in present-day Sweden, was an important Viking Age trading center which handled goods from Scandinavia as well as many parts of Continental Europe and the Orient. Björkö is located in Lake Mälaren, 30 kilometers west of contemporary Stockholm, in the municipality of Ekerö.

Hovgården is an archaeological site on the Lake Mälaren island of Adelsö in Ekerö Municipality in central-eastern Sweden. 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 which kings and chieftains ruled the area. Hovgården, together with Birka became a UNESCO World Heritage Site in 1993.
