The square was created in the dense urban web of the Presqu'île at the same time as the Rue Impériale (now named Rue de la République) in the second half of the 19th century when major works were led by the Prefect of Rhône Claude-Marius Vaïsse.
[1] Originally, there was a fountain at the centre, flanked by two flower beds and trees at the east and the west.
Then in the early 20th century, a statue of Sadi Carnot (assassinated nearby) and planes were added, but removed in 1974 during the construction of Lyon Metro Line A under the square.
A traboule/shopping mall from the Rue du Président-Édouard-Herriot also provides an access to the square: the Passage de l'Argue.
[2] The Place de la République is now composed of two kiosks, a glass carousel, two large plane trees and benches (at north).
