Kalix Church is the northernmost medieval church in Sweden. It dates from the 15th century (first mentioned in 1472). Several items of medieval inventory are preserved including the font, altarpiece and two sculptures. The pulpit, a Baroque work, is from 1674, and is among the oldest to be found in the north of Sweden. The church has a separate wooden belfry, which was made in 1731. The church has been sacked by Russian troops twice, in the 18th and 19th centuries; the adjacent church cottages were burnt down.
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.
