The monument also contains the remains of an unknown soldier of the Napoleonic wars; as you see on one side there is an enthusiastic endorsement of Napoleon in the local language, and on the next side is this poem:
Sous cette pierre nous avons déposé tes cendresThis country's gratitude for past assistance from France is not well known even in France, let alone elsewhere. I can't imagine that there is any other capital city where Napoleon is so enthusiastically venerated (certainly not Paris, where I have always sensed a certain ambivalence).
Soldat sans nom de l'armée napoléonienne
Pour que tu reposes au milieu de nous
Toi qui en allant à la bataille pour la gloire de ton empereur
Es tombé pour notre liberté
OK, folks, no sneaky googling: which capital, and which country, am I talking about?
(For a bonus: which ruler of nineteenth-century France is buried in this same country?)
