The first name of Saint-Cyr-sur-Menthon

Saint-Cyr-sur-Menthon originally bore another name to designate the parish. The primitive appellation was Tournas, before the village took the name of the young Christian martyr of the 4th century Saint Cyricus of Tarsus. Today, this ancient appellation subsists in the form of Tournaz, which designates a locality whose hamlet takes the name of Tournô in Bressan.
