The Temple at Uppsala was long held to be a religious center in the Norse religion once located at what is now Gamla Uppsala, Sweden attested in Adam of Bremen's 11th-century work Gesta Hammaburgensis ecclesiae pontificum and in Heimskringla, written by Snorri Sturluson in the 13th century. Uppsala has for long been exposed to fanciful theories about the implications of these descriptions of the temple and of the findings of archaeological excavations in the area, now including recent findings of extensive wooden structures and log lines from the 5th century which allegedly played a supporting role to activities at the site, including ritual sacrifice. According to sources from the later middle ages the temple was destroyed by King Inge the Elder in the 1080s, but there are no contemporary sources to support that.

Harthacnut or Cnut I was a semi-legendary King of Denmark. The old Norse story Ragnarssona þáttr makes Harthacnut son of the semi-mythic viking chieftain Sigurd Snake-in-the-Eye, himself one of the sons of the legendary Ragnar Lodbrok. The saga in turn makes Harthacnut the father of the historical king, Gorm. It has been suggested he is to be identified with the Hardegon of Northmannia whose early-10th century conquest of Denmark was related by Adam of Bremen.
