The St. Cosmas and Damian church in Wiarden, constructed in the early 13th century, is an exemplary Romanesque structure built from granite blocks. Over the centuries, significant architectural modifications were made, including the replacement of the original eastern apse with a larger choir in the late 15th century, incorporating elements of a polygon to enhance its spatial capacity. This church also features exquisite late 15th-century wall paintings of life-sized saints under canopies, adding to its historical and artistic richness.

In 1808, Johann Gerhard Schmid, a respected organ builder recommended by knowledgeable authorities, constructed an organ for this church under a contract signed in 1806. This organ, initially featuring an independent pedal and 14 speaking stops, has undergone several modifications and restorations, shaping its present form largely defined by the 1963 redesign by Alfred Führer. This redesign included the removal of a second manual added in 1908 and a reconfiguration of the organ's disposition, maintaining its historical essence while adapting it to modern use. Over the years, these adaptations have preserved the unique sound and functional integrity of the instrument, making it a valuable piece of the church's musical heritage.
