🛡️ **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.

🧱 **Tour aux Puces** – Thionville's Oldest Building** The **Tour aux Puces** ("Powder Tower") is a medieval fortified tower dating back to the 11th century – and the oldest surviving building in the city. Originally part of a castle complex, it has served over time as a defense tower, a prison, and now houses a **City Museum** with an archaeological collection. 🏺 Inside, you'll find exhibits from Roman, medieval, and early modern periods – from ceramics to weapons to religious objects. The tower probably got its name from a mistranslation from German to French (“Powder Tower” became “Powder Tower”). **Tip:** The tower is cool and quiet – perfect on hot days. From the top, you have a small but excellent view over the old town. Combine it with the Belfry and the Église Saint-Maximin for a historical tour.

💧 Plan d'Eau de la Sangsue – Small Natural Lake Tucked away in the countryside lies the Plan d'Eau de la Sangsue, a small natural lake with wild shoreline vegetation, calm waters, and a natural charm. While its name ("Leech Pond") is unusual, the body of water is a peaceful spot for walkers, nature lovers, and birdwatchers. 🌿 Surrounded by forest and meadows, the pond is a refuge for amphibians, insects, and waterfowl. A narrow path leads along the shore – ideal for a quiet break in nature. Tip: Particularly beautiful in spring or when there is light fog – then the pond appears almost mystical. Perfect for a quiet rest off the beaten track.

This emblematic 14-sided tower stands on a 2.5 to 3 m high circular foundation, in which many authors have suggested the remains of a Carolingian chapel. The tower is said to have actually been the keep of a castle built by the Counts of Luxembourg in the 16th century, corresponding to the size of the present castle courtyard. It served successively as a residence and last refuge in the event of an attack, as an armory, a prison, and finally, in 1905, as a museum.
