History
The history of Adelsö began with the
Stone Age

that were to become Adelsö lay beneath the
Baltic Sea.
Fishing, bird- and
seal-hunting created the foundation for the life of the people living there. Graves from the early and late Stone Age exist, but most of the gravesites date from the
Iron Age, mostly the
Viking Age. There are also two ancient
hillforts (''fornborgar'') on Adelsö; one of them, situated on Skansberget near Stenby, is unusually well-preserved.
Adelsö, earlier called ''Alsnö'' or ''Alsnu'' reflects the importance of the area during the Viking Age. The King's House (''Kungsgården'') was next to Hovgården and the monarch ruled over the nearby city of
Birka. This is also the site of ''Kungshögarna'' at
Hovgården. ''Kungs'' means king or royal and ''högarna'', from the
Old Norse word ''haugr'', means mound or barrow.
During the latter part of the 12th century, a Christian church was built next to Hovgården.
Birger Jarl's sons built
Alsnö hus, a splendid castle where
King Magnus I in 1279 assembled the ''Meeting of Alsnö''. At that meeting, the ''
Ordinance of Alsnö'' was established, introducing the privileges of the Swedish
nobility.
During the
Middle Ages, Alsnö hus was used as a summer palace for kings and
governors but later fell into ruin. What remains of the castle and several graves near Hovgården was excavated during archeological digs conducted between 1916 and 1926.
