The present stone church was built during the second half of 1400s, but the vestry may date from the 1200s. The church is decorated with well-preserved frescoes made by so-called "Edebo master". Paintings depict events from the Old and New Testament. The porch was built in 1514.
A bell tower stands on the other side of the highway northwest of the church. The large bell was cast in 1625.
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.
