A very interesting fortification. Even when it's closed, it still looks impressive.

Built between 1902 and 1904 by Gustave Eiffel. Destroyed in 1940 by French troops, the viaduct was rebuilt identically in 1949.

One of the large facilities, with bunkers spread over several kilometers. The ammunition and personnel entrances in the pastures next to the path are clearly visible. Entry strictly prohibited. Vandals cleared everything out, however.

Ammunition and crew entrances, with domes. Access strictly prohibited. Lies in a pasture with cows that have young animals with them. A deep shaft secured with barbed wire. https://youtu.be/stpHB1_IWyM

In the middle of the fields on a hill, visible for miles. Without explaining its meaning and without an obvious connection to any installation. A thick concrete slab on its base reveals crampons that lead into the dark. In my opinion it had something to do with the bunkers of the Maginot line, but is not mentioned anywhere in the records. Was too risky for me to get in without equipment. It is also prohibited. Bad roads to the tower.

A strategic road designed to supply the various bunkers in the section from Crusnes to Morfontaine. Walk past the Serrouville airport, which is used by hobby pilots. There is more traffic on the airfield than the condition of the road suggests. The street has a very stable substructure, but the ceiling has lost its tar for a long time and is more like a slope. Huge puddles, especially after rains, but all have firm ground. Go straight past the bunkers in Bréhain. Very long way through the forest that only crosses a road once. In places meanwhile gravelly, but can be used by all bicycles. Except racing bikes. Crosses the former railway line from Aumetz to Audun, the rails are still lying. If you find them, however, you are GOOD.
