This tour heads a few kilometres north of the city to Gamla Uppsala, or Old Uppsala, one of the most important ancient sites in Scandinavia. Here great royal burial mounds rise from the plain, marking the graves of legendary kings and the centre of pagan worship and power in the Viking age and before. With a guide and an excellent museum to explain the myths, rituals and archaeology, it is a fascinating and evocative journey into Sweden’s deep past and the origins of the nation, and a highlight of any visit to Uppsala.
