Michel Stiehr Organ

The organ of the Saint-Louis church is attributed to Michel Stiehr, an organ builder, in 1817.

However, this instrument has undergone significant transformations over time. It was first modified by Koulen in 1882, then by Kriess in 1920, and finally by the Steinmetz brothers in 1983. The case, made of oak, features side elements added in 1920.

It is distinguished by its structure composed of four flat fronts and three turrets, the latter topped with half-relief urns. This organ can be classified as a "neo-classical" style instrument.
