🛡️ **Ouvrage du Hackenberg** – The Largest Fortification of the Maginot Line** The **Ouvrage du Hackenberg** near **Veckring** is the most impressive and largest fortification of the **Maginot Line** – a real must-see for history buffs. Built between 1929 and 1935, it includes: 🔩 **17 combat and entry blocks**, 🚇 over **10 km of underground tunnels**, 🚂 an **internal electric railway**, ⚙️ barracks, ammunition depots, a hospital, and a power supply. During World War II, the fort was combat-ready, but was evacuated without a fight after the armistice in 1940. The French Army later reused the facility during the Cold War. 🎟️ Today, Hackenberg has been beautifully restored and can be visited on guided tours – including a ride on the original narrow-gauge railway. Tip: Be sure to take a guided tour – it lasts about two hours. The underground coolness is pleasant even in summer! It's ideal for a half-day excursion with a historical twist.

🛡️ **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.
