The old Pont de Cattenom between Cattenom and Kœnigsmacker over the Moselle consisted of Whale pontoon bridge elements from Arromanches in Normandy from D-Day 1944. After the reconstruction of the Moselle bridge in 2019, numerous historical metal parts were returned to memorial sites of the Allied landings in Normandy. A small bridge on the cycle path and an information board commemorate the old Pont de Cattenom. https://fr.wikipedia.org/wiki/Pont_de_Cattenom

🛡️ **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.
