An inscription refers to the first consecration of the church in 1199. The nave has a flat ceiling and is equipped with oylets. The choir has a semi-circular, vaulted apse with a Majestas representation and two well-preserved Evangelist symbols. There are traces of frescoes dating back to the 13th century. To the south of the triumphal arch appear the victims of Cain and the upper body of a fish-tailed siren. The head with long hair, the thoughtful expression and the gestures of the arms give the depiction a uniquely melancholic appearance, which contrasts significantly with the image of the demonic element in the other wall paintings.
The Church of S. Nicolaus is open from 14.04.2023 - 13.10.2023 every friday at 2 pm for the guided tours in german and italian language.
