a tall tower with a statue on top of it

One of the four main sculptural groups on each of the pillars of the Arc de Triomphe. This one is titled "La Paix de 1815," and per Wikipedia, "by Antoine Étex commemorates the Treaty of Paris, concluded in that year." Per https://www.flickr.com/photos/wallyg/1427820633, "The sculptured high relief, executed by Antoine Etex, represents the return of peace after the Treaty of Paris in 1815 which brought an end to Napoléon's attempt to return to power during the One Hundred Days. It constitutes a logical pendant to La Résistance de 1814."
