The church was a pilgrimage destination for people with epilepsy and therefore has carved wooden laity stalls, including one decorated with the "Gerechtigkeitsspirale" (Spiral of justice).

[1][2] The church is dedicated to St. Valentine, the patron saint of people with epilepsy (Fallende Krankheit) and lovers, housing relics which came in 1350 from Eberbach Abbey to Kiedrich.

[1] The main entrance in the west front is topped by a tympanum which shows both the Annunciation and the Coronation of Mary.

The pews are decorated with carvings of ornaments, flowers, vines and inscriptions in Gothic alphabet.

[7] They perform a special Germanic version of Gregorian chant,[1] once every Sunday except during summer vacation.

The English Baronet Sir John Sutton financed a renovation, performed from 1858 by the Belgian organ builder August Hooghuys from Bruges.
