The main facades depict the battles of Fleurus, Héliopolis, Marengo and Austerlitz. The two bas-reliefs under the portico depict "the call to the defense of liberty" (David d'Angers) and "the return of the victorious heroes" (Ramey). Eight giant allegorical statues, almost 3m high, were placed in the "attic" representing the Virtues. On the north facade David d'Angers completed "Devotion", "Prudence", "Resignation" and "Fortitude" in 1835; Ramey only finished "Vigilance", "Clemency", "Energy" and "Temperance" on the south facade in 1839. Unfortunately, because the stone was not properly weather-proof, the statues started to erode. In 1921 they were repaired using reinforced concrete; nevertheless in 1937 six of the heads rolled off onto the street below. In later restoration of the arch in 2003, only four of the statues were kept, those of David d'Angers, on the north facade.
