Although Gehren belonged to the parish of Holzgau, but this affiliation brought with it a wide church walk, they participated in the maintenance of the Warther parish, as well as in the construction and maintenance of the church, which was finally rewarded with the incorporation of the church in 1626. The chapel "St. Nikolaus" in Gehren was then built in the 19th century, because the Warther neighboring settlements Gehren and Lechleiten were considered very wealthy at that time.
