Traenheim Lutheran Church

The Protestant church of Traenheim, built between the 11th and 12th centuries, retains traces of its origins with its foundations and bell tower, although few elements from that era remain. The flat-ended choir, constructed later between the 13th and 14th centuries, reflects the architectural evolution of the site. Several modifications marked the building's history, notably in 1508, 1556, and 1912, while preserving a rare Gothic window in Alsace, located in the southeast corner of the nave, an unusual spot for such an opening.

An 18th-century organ adorns the church interior, adding further heritage value. Excavations in the 20th century uncovered a significant amount of bones beneath the nave and bell tower, suggesting the church may have been built on an ancient cemetery or near a primitive early Christian sanctuary. The porch tower is the only element to have escaped successive transformations.

Between 1690 and 1913, the church housed a simultaneum, sharing its use between Catholics and Protestants, with the choir reserved for Catholic worshippers for 223 years.
