The church of St Peter and Paul in Weimar, Germany, is also known as Herderkirche after Johann Gottfried Herder. It is the most important church building of the town, and is called Stadtkirche, opposed to the courtly Schloßkirche. It has been the church of a Lutheran parish since 1525, after the Reformation. The church is part of the World Heritage Site Classical Weimar, together with other sites affiliated with the Weimar Classicism movement. Inscribed on the World Heritage List in 1998, these sites bear testimony to the cultural importance of Weimar during the late 18th and 19th centuries and the outstanding architecture that arose in response to the cultural values of the time.
