The Mont Valérien monument stands against the fort's southeastern glacis. It forms an outer wall of Vosges pink sandstone, over 13 feet high and 300 feet across.
Sixteen studs, corresponding to the 16 tombs of the crypt, are spaced at regular intervals along it. Each is decorated with allegorical motifs in high-relief bronze.
A 40-foot Cross of Lorraine stands at the centre of the monument. Before it, an eternal flame burns in a bronze brazier.
