🛡️ **Ouvrage de Kobenbusch – Mighty Fortification of the Maginot Line** The **Ouvrage de Kobenbusch**, located south of Cattenom near the Luxembourg border, is one of the large underground fortifications of the **Maginot Line**. It was built between 1930 and 1935 and consisted of several combat blocks, underground connecting tunnels, a barracks, ammunition depots, and machine rooms – on several levels, anchored deep in the limestone. ⚙️ Particularly noteworthy: The technical systems were designed to be self-sufficient for months – including power generation, ventilation, a kitchen, and a hospital. The fort was occupied without a fight during World War II, continued to be used in part after the war, and is now privately owned. 🚷 It's **not open to the public**, but some ventilation towers and blockhouses are still visible in the forest near the D64 road (between Cattenom and Berg-sur-Moselle). **Tip:** For Maginot fans, a walk through the forest is worthwhile – with a little research, you'll find several bunker remains. Respect barriers, as some entrances are unstable or secured.

🛡️ **Ouvrage du Galgenberg – A Deep Look into the Maginot Line** The **Ouvrage de Galgenberg** is a large underground fortification of the **Maginot Line**, located south of Cattenom. It was built between 1930 and 1935 and served to defend the French border against Germany. The complex consists of several **combat bunkers**, **barracks**, **tunnels**, and **supply facilities** located deep underground. During the Cold War, the fort was modernized and remained in active use until the 1980s. 🔦 Today, it is accessible for guided tours (registration only), including a view of the original equipment: rails, power supply, ventilation systems, and gun emplacements. **Tip:** Ideal for military and history buffs – bring warm clothing, as it's chilly inside! Guided tours with former soldiers or experts are particularly impressive.

🚧 **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.

Berg Castle, built on a hill above the town of Nennig, consists of two connected former moated castles. The lower castle is privately owned and is gradually falling into disrepair, while the upper castle, converted into a palace during the Renaissance, houses a hotel, a restaurant, and a casino. The upper castle, incidentally, was almost completely destroyed in World War II, rebuilt by the Saarland in the 1950s, and used as a school camp for about 30 years. It was only converted into a hotel in the late 1980s. Details about the history online: https://de.m.wikipedia.org/wiki/Schloss_Berg_(Saarland)
