The first traces of thetown’s history date back to 770. Since then, the town’s heritage has grown from strength to strength. In the 18th century, Louis de Cormontaigne, following in Vauban’s footsteps, fortified the town of Thionville with the construction of the Couronné de Yutz, two lock bridges and the Porte de Sarrelouis. The town jealously guards the last Altar of the Fatherland, erected on September 22, 1796, and classified as a Historic Monument of the French Revolution. And if you’d like to find out even more about this city rich in history, we recommend a guided tour of Thionville.
