The current Jelling church was built of limestone around the year 1100. Archaeologists have found traces of three earlier wooden churches on the site. The first wooden church built on the site of the present edifice was the largest of its kind anywhere in Scandinavia. Archaeological evidence suggests that it was built in the later 10th century, during the period around 960 when Harald Bluetooth introduced Christianity into Denmark, as he proclaims on the larger of the two runic stones.
The part of the church burned down in 1679 and it was restored with a new porch. The pulpit dates from the 1650s. Mural paintings were in bad shape until Julius Magnus Petersen replaced them with copies in 1875. Jelling church is part of the UNESCO World Heritage site with Jelling mounds and runestones.
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.
