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:The Chapel of St. Martin is the only completely preserved Romanesque building in Vyšehrad and one of the oldest in Prague. In was built around 1100 in the eastern part of the fortified outer ward. Between 1100 and 1300, the Rotrunda was surrounded by a cemetery. The building survived the Hussite Wars and was used as the municipal prison of the Town of the Vyšehrad Hill.
During the Thirty Years’ War, it was used as gunpowder storage, from 1700 to 1750, it was renovated and reconsecrated. In 1784, the chapel was closed passed to the military management which kept using it as a warehouseand a cannon-amunition manufacturing facility. In 1841, it was meant to be demolished to give way to the construction of a new road through Vyšehrad. Eventually, only the original western entrance was walled up and replaced with a new one in the sountren side. The dilapidating Rotunda subsequently served as a shelter for the poor.
