🛡️ **Fort de Guentrange – German Fortification above Thionville**
The **Fort de Guentrange** was built between 1899 and 1906 by the German Reich Army when Thionville (then Diedenhofen) was part of the German Empire. It is one of the best-preserved forts along the Moselle River and part of the so-called **Moselstellung** – a defensive line against France.
🔩 The fortress is strategically located above the town, overlooking the Moselle Valley. It consists of underground passages, casemates, ammunition depots, and observation towers – some still with their original furnishings.
🎖️ Today, the fort is a museum (accessible only with a guided tour) and offers fascinating insights into military technology, the daily lives of soldiers, and European border history.
**Tip:** Tours usually take place on Sundays – check in advance! The path to the fort already offers great views and is a good hiking stage with a historical destination.
