[1] The square was modified when the Quai Fulchiron was created in 1858, then expanded after the destruction of houses that prolonged the Rue Lavarenne.
Similarly, while digging the tunnel which connects the parking under the rue Monseigneur-Lavarenne, several buildings of the Middle Ages were discovered, apparently abandoned after the many floods of the Saône.
[6] The square was formerly named Place du Port-Sablé (also spelled Sablet, which perhaps referred to the sandy nature of the soil or the unloading of vessels which contained sand).
[12] The majority of the square consists of two rows of four to six-storey buildings with narrow facades generally built in the 19th century.
[2] After having served for a while as a station for trolleys and buses, the square was gradually transformed into a large garden through a space reorganization.
