Himmelev Church dates probably from the late 1100s and it was built in Romanesque style. The tower and arches were added around 1300 as well as Gothic style windows. The tower was rebuilt of brick around 1550. The oldest item in church is a crucifix from the 1300s. The font dates from 1625 and pulpit from 1630. The altar was made by Anders Nielsen Hatts workshop in Roskilde in the early 1600s.
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.
