St. Peter's Church Bosau
St. Peter's Church Bosau, once known as the "white marble cathedral", is a late Romanesque fieldstone church founded by Bishop Vicelin in the 12th century. Today, an oak figure of the bishop can be seen on the east wall of the choir. The church is idyllically situated on the shores of Lake Plön and is known for its white sheen, which was created by the plaster mortar from the Kalkberg mountain that was used to encase the fieldstones. Today, a coat of lime paint is used to even out the damaged plaster surfaces. St. Peter's Church in Bosau has undergone a number of changes over the centuries. During the Thirty Years' War, it was partially destroyed and rebuilt in the Baroque style, with the original round tower being converted into a square one and topped with a Baroque dome. Inside the church, the late Gothic triumphal cross and the three-winged altarpiece from the 14th century, which is considered one of the oldest oak altars in northern Germany, catch the eye. The altar shows carved scenes of the Last Judgement and during Passiontide the portraits on the back of the altar can be seen.
