Hedrum Church was built of stone around 1100 and has 260 seats. The church has a rectangular nave, square choir and apse. Archaeological excavations show that the apse is added later. The structure was extended by four meters in 1666. The west part with the portal and door openings are from after the Reformation. Hedrum Church has a number of tombstones, which cover large parts of the floor of the church. Hedrum Church cemetery is clearly visible from traffic arteries on both sides of Numedalslågen. Some of the graves are believed to pre-date the introduction of Christianity confirming the supposition that ancient pagan cult sites were chosen as the venue for the earlier churches.
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.
