Valsgärde or Vallsgärde is the ancient centre of the Swedish kings and of the pagan faith in Sweden. The present farm dates from the 16th century. The farm's notability derives from the presence of a burial site from the Swedish Vendel Age. The first ship burial is from the 6th century and the last graves are from the 11th century.
The site was found and excavated by archaeologists in the 1920s, and before this similar graves had only been found at Vendel, which gave its name to this period of the Scandinavian Iron Age. The graves are princely, and are almost identical to ones found later in England, at Sutton Hoo in East Anglia. There are several theories about the identities of those buried, ranging from the Ynglings (Scylfings) to powerful warriors within the Leidang system, or local strongmen who had enriched themselves through trade due to the area's strategic position between the fjord of Mälaren and the important region of Tiundaland. There are so many rich graves that it is unlikely that most of them were royalty.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
