Originally Reichenbach was part of the parish of Aeschi bei Spiez. During the 15th century the chapel of St. Nicholas was built in the village. The chapel was first mentioned in 1453 and rebuilt in 1484. During the 18th and 19th centuries it was renovated and expanded. After Bern accepted the Protestant Reformation, Reichenbach converted to the new faith in 1529 and created its own parish. A filial church was established in the village of Kiental in 1929, while Wengi and Schwandi are still part of the Frutigen parish.
