In written evidence, a castle chapel is mentioned, which is located halfway between the town of Neuenbürg and the castle. Presumably the church already existed in 1290. After the catastrophic city fire of 1783 it was used as a parish church for a short time. Because of its late medieval wall paintings, the church is one of the most important architectural monuments of the 14th century in Baden-Württemberg. The picturesque half-timbered storey of the tower, on which the medieval construction technology is still recognizable, is characteristic. One of the most beautiful places in the city is the old cemetery in front of the church. From there, especially in the afternoon sun, you can enjoy the view down to the city.
