Kuninkaanhauta ("King's Grave") is the largest Bronze Age cairn in Finland. The stone huddle is 36x30 meters wide and four meters high. According the legend a local king or chief is buried to the cairn. It's quite probable several burials are made to Kuninkaanhauta during decades or centuries and it's expanded little by little. There has been no actual archaeological investigations on the site, but some remains of the Bronze Age place of residence have been found.
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.
