The Obstalden church was first mentioned in 1444. In 1528 the Kerenz population converted to the Reformation; In 1593 she bought herself from Schänis and formed the independent parish of Kerenzen. From the beginning, the church in Obstalden was the parish church for all three Kerenzerberg parishes. Around 1460, the paintings were made on the south wall of the choir. In 1479 and 1516 two bells came into the tower, calling St. Fridolin and the "Rex gloriae" for help. All altars and pictures were removed on the occasion of the Reformation. The first organ sounded in 1809.
The wall paintings in the tower choir are the oldest surviving example of monumental painting in the canton of Glarus. Despite the many flaws, the murals mean a happy win for Glarus and the region. To date, traces of old wall paintings have only been found in Matt, Betschwanden and Schwanden in the canton, but these could not be made visible. What we have preserved to this day are only scant remains of a once colorful painting that covered the choir with the vault and probably all the walls of the rest of the church.
