On leaving the Citadelle, turn right and go down the slope towards the Meuse and the Rue de Rû, keeping to the right. Go by the stores and then the octroi where the shops are located, and enter the Citadelle by No. 4 listening-post, to visit some of the caverns fitted up as they were in the war.
Here can be seen in particular, under a military guide, the chamber of honour where were laid to rest in November 1920 the bodies of 8 unknown soldiers, from among whom was taken the Unknown Warrior who rests in Paris beneath the Arc de Triomphe.
