Gjerpen church is one of the oldest churches in Norway. It is believed the church was consecrated 28 May 1153 to the apostles Peter and Paul. The church represents the Romanesque style with a cruciform plan after the later additions. The church was extended in 1781 and 1871. The new interior was made by Emanuel Vigeland (1875-1948), this includes the mosaic 'Den bortkomne sønns hjemkomst', glasspaintings, pulpit, baptismal font, benches, lamps and a bronze relief that was drawn in the 1920s. Architects in later time has also included C.Christie and H.Bødker. Vidkun Quisling was buried in the church graveyard after his execution in 1945.
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.
