🛡️ **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.

The Roman Villa Borg is a fascinating open-air archaeological museum. Built as a fully reconstructed villa rustica based on a Roman model, it provides visitors with an authentic picture of life in the Roman Empire. The complex features faithful replicas and archaeological finds that bring the past to life. A special highlight is the Roman tavern, where you can enjoy historical dishes. The workshops also offer unique insights into ancient craftsmanship, which you can experience up close.

Very beautiful castle with sometimes exciting exhibitions and events. At an event organized by the University of Metz, I was able to experience an interesting tour there with a great dinner in the large hall. The meal was accompanied by a lute ensemble.
