🚧 **Barrage du Lac du Mirgenbach – The Technical Heart of the Lake** At the southern end of **Lac du Mirgenbach** is the **dam (barrage)**, which serves to regulate the water and cool the nearby **Cattenom Nuclear Power Plant**. The facility is not open to the public, but is easily visible from the paths around the lake. 🌊 The dam marks the transition between technology and nature: Here, the water flows in controlled channels, creating an exciting interplay of industrial function and scenic tranquility. **Tip:** Those who walk the circular path around the lake have a good view of the dam from the eastern shore – particularly interesting for technology enthusiasts and landscape photographers.

https://www.siercklesbains.fr/index.php/le-camping A very beautiful and well-kept campsite right on the banks of the Moselle with a wonderful view of the "Château des Ducs du Lorraine" For cyclists with tents there are 7 pitches delimited by hedges. In the reception area there are beer tables and benches that can be taken to the pitch. Since the place is very small, we recommend booking in the evening 2 days in advance. . . It is worth it!
