The medieval Kirkkonummi brick church was built in the 15th century. The local parish was established in 1240 and there have been several wooden churches at the same site before. The present church has been renovated and modified several times. In 1570s Russian soldiers damaged church and it was burnt by lightning. Next renovations were made in 1637 and again in the 19th century.
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.
