The Church; and the Old Deist Burial Mounds
Gamla Uppsala was a renowned ceremonial site for multi-deist Sweden, a place of religious rites, royal burials and palaces, and a spiritual center in the 11th Century, when a Christian Cathedral was constructed there.
1. The Church
The form of the church remaining is about half the original size, see http://www.raa.se/cms/en/places_to_visit/gamla_uppsala/history_of_gamla_uppsala.html/. It was built over the earlier multi-deist structures there. See http://www.sacred-destinations.com/sweden/gamla-uppsala.htm/
It was in the ordinary course pf business for Christianity to usurp the spirituality of the conquered, and make its own inroads, like a piggyback where possible; or force itself and then call the resulting brainwashed citizens "converted" -- but it is a sadness and loss to history all the same. The might of the conqueror is not always an indication that they are in any way "divinely promoted." The old ways may well have suited the culture and topography better.
Multi-deism remains part of Christian culture as well. Just call the Trinity One. Common sense applies theological sleight-of-hand. Add "evil" and demons, see that even God couldn't control the borders of Eden, and we are not far from the old ways.

Old Uppsala is near Stockholm, the city on the archipelago at the deep fjord. Go to Old Uppsala and be reminded of the greatness of ancient Sweden, see http://www.theancientweb.com/explore/content.aspx?content_id=32/
1. Founder perhaps
Read at that site that Odin decreed, in the Norse god's wisdom, that the dead shall be burned in a great crematory fire. The Odin there, however, is probably one Sigge Fridulfson, the great and very human leader of a migration north from the Caucasus a millenium ago, who took the name Odin for himself to pave his own way, see Bogomilia: Sigge Fridulfson. Wise, and it worked.
We found no tribute to the brilliant ruler, Sigge Frudulfson or Fridulfsson.
It was only after we returned that we found his name connected to one of the earliest migrations north from the Caucasus, and who took the name of Odin so that his and Odin's became one in reverence. His sons were placed on the thrones in Scandinavia, and he was a fierce but wise ruler. See Sigge Fridulson, Sigge Frieulfsson, Origin of the Swedes
2. The site mounds.
Overall, the site is a long wandering line of huge mounds, some excavated. There were no large treasure troves found, but sites of cremations and some artifacts showing the prominence of those resting there. Swedish people are not inclined to make Disney out of their traditionally meaningful sites, so there is little fanfare at Gamla Uppsala. It is largely left to age naturally. Excellent. No hype.
Tales tell of a large tree at the site, and a deep well, and rituals for centuries there.
There are no display stands, or marker tablets directing your view. That to us was refreshing. There is time to let it all sink in, and then look details up later, or in time at the small museum there.
