The Monument à la République was inaugurated in 1883. Léopold Morice is the sculptor. 

The bronze on the pedestal is Marianne. She is an allegorical figure of the French republic. 

Three stone female figures, also allegorical, flank the pedestal. They are La Liberté, L’Égalité et de La Fraternité. A bronze lion symbolizing universal suffrage stands at Marianne’s feet.

A bust of Marianne is present in every state school. Marianne wears a phrygian cap. 

I think this fact is interesting because phrygian was somewhere in the middle east. The bonnet is considered to be of anatolian origin. This hat became a symbol during the revolution because it represents the pursuit of freedom. Emancipated Roman slaves wore a similar hat.
