According to Swedish official sources the city was founded in 1612, when the former settlement at Kungahälla was moved to the Bohus Fortress. However, this is disputed due to the fact that other sources indicate that it was the capital of Norway at one point under Sigurd I Magnusson, something frequently used for marketing and tourist purposes. For example, due to this mythical history, Kungälv could celebrate its "1000 year anniversary" in 1959 
Sigurd I Magnusson (Sigurd Jorsalfare/Sigurd the Crusader) was the King of Norway (1103–1130) and is the most well known crusader king of Scandinavia. He was also the first European king to join the crusades at a time where Kungälv was Norwegian territory.
Sigurd returned to Norway in 1111 where he made his capital in Konghelle (in the vicinity of Kungälv in present-day Sweden) and built a castle there, where he kept a relic given to him by King Baldwin, a splinter reputed to be from the True Cross. Sigurd died in 1130 and was buried in Hallvardskirken (Hallvards church) in Oslo.
In the 1120s Pomeranian ships from Szczecin, from the southern coast of the Baltic Sea attacked the Danish coast. On 10 August 1135 Duke Ratibor assaulted the Norwegian towns. Konghelle, was captured and burnt to the ground by the forces of prince Ratibor, assisted by a fleet of 550 ships with cavalry on board (each carrying forty-four men and two horses). They laid the town in ruins, killed a large part of the population, and abducted most of the survivors as thralls to Szczecin. Snorri Sturluson, writing a century later, said that Konghelle never completely recovered.
The Bohus Fortress together with cookie and biscuit store "Bräckboden" are the most popular tourist attractions in Kungälv.
