Origin of Mondorf-les-Bains ?
The origin of the name Mondorf-les-Bains goes back to the Carolingian dynasty, i.e. Frankish kings. Charlemagne had a niece called “Muomina”, who donated all her possessions to the abbey of Echternach. Among these possessions was the small village, which thus took the name of “Muomendorph”. Charlemagne married Hildegarde de Thionville. As a result, he was forced to travel frequently between Thionville and his small capital of Aachen, and had a residence (“Pfalz”) built in Mondorf, which served as a relay.
A border village between France and Luxembourg, the toponymy of Mondorf has varied over time : Muomundorf (960), Mamendorf (1030), Muomendorph (1060), Mumendorf (1161), Mundorf (1572), Mondorf (1681), Mendorf (17th century), Mondorf (1793), Mondorff (1801).
