The first wooden church of Kristiinankaupunki was built between 1654 and 1658 on the site where the Ulrika Eleonora Church now stands, however it burned down on 16th June 1697. The building of the Ulrika Eleonora Church, which replaced it, was completed in 1700. The church was renovated and returned to use in 1965. The wooden church is a typical seaside church complete with a votive ship hanging from the ceiling. The ship building skills are also otherwise evident in the architecture of the church, for example in the ceiling structure. Outside the church is an old graveyard where the significant families of the city are buried. This churchyard also holds the graves of warriors of Kristiinankaupunki. Only a few services are held in the church each year. Ulrika Eleonora is a popular venue for summer weddings.
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.
