Under the arch there is the Tomb of the Unknown Soldier, with its eternal flame that is rekindled every evening by ex-servicemen's associations. The headstone commemorates the unknown soldiers who died in The Great War, to which those lost in the Second World War have been added, and as you can see, the locations of the great battles of the Revolution and the Empire are engraved on the inner surfaces of the column. The inscriptions on the inner surfaces of the small arches record the names of hundreds of important figures from the same period. You will notice that some of the names are underlined; these are the ones who died in combat.
