Square Capitan next to the Arènes de Lutèce is named after doctor, anthropologist and historian Louis Capitan, who redesigned it in 1916 in the style of a formal Italian garden.
The 12,168-sq.m. square was built over the Saint Victor tank, which was used in times past to collect and store water from the Canal de l'Ourcq. A 1924 statue of a headless nymph reclines inside the square’s small water feature.
