The history of Adelsö began with the [[Stone Age]]. Adelsö at that time consisted of small islands which emerged from the sea at the end of the [[Last Glacial Period|Ice Age]]. Mälaren, a [[freshwater]] lake, did not yet exist, so the [[skerry|skerries]] that were to become Adelsö lay beneath the [[Baltic Sea]].

Fishing, bird- and [[Pinniped|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 [[hillfort]]s (''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 Ladulås]] 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 [[governor]]s 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.
