Anundshög is the largest tumulus in Sweden. It has a diameter of 60 metres and is about 9 metres high. Assessments of the era of the mound vary between the Bronze Age and the late Iron Age. A fireplace under it has been dated by radiocarbon dating to sometime between AD 210 and 540.
Some historians have associated the mound with the legendary King Anund, while others regard this as speculative. It is purported also that the name is taken from the large runestone at the site, the central stone in a row of 15 alongside the mound, re-erected in the 1960s and apparently marking out the route of the Eriksgata. The inscription on the runestone reads: "Folkvid raised all of these stones after his son Heden, Anund's brother. Vred carved the runes."
At the foot of the mound are 2 large stone ships placed end to end, 51 metres and 54 metres long. The site was a thing-place and the ship settings may be associated with this function.

Before the arrival of Christianity in Sweden, Gamla Uppsala was the seat of Swedish kings and a ceremonial site known all over northern Europe. The settlement was home to royal palaces, a royal burial ground, and a great pagan temple. The Uppsala temple, which was described in detail by Adam of Bremen in the 1070s, housed wooden statues of the Norse gods Odin, Thor and Freyr. A golden chain hung across its gables and the inside was richly decorated with gold. The temple had priests, who sacrificed to the gods according to the needs of the people.
The first Christian cathedral was probably built in the 11th century, but finished in the 12th century. The stone building may have been preceded by a wooden church and probably by the large pagan temple.
