A day trip to Lorraine, France.

The Maginot Line, two of its many Ouvrages Cattenom and Hackenberg provide the subjects.

Hackenberg provided a guided tour par excellence, to an underground battleship of a fortress. Its military museum is a hidden treasure trove. Its scale and conception is awesome. As a museum concept, Hackenberg gives us a working underground railway, fully serviceable  gun turrets, and a 2 hour guided tour worth every cent.

In addition the surrounding picturesque country-side has been left wild, to add a further shroud to the hidden nature of the museum itself.
