Thiers wall
The station is named after the "Porte d'Orléans", a gate in the nineteenth century Thiers wall of Paris, which led to the town of Orléans via the road now known as route nationale 20, or N20. Its subtitle is for the World War II general Philippe Leclerc de Hauteclocque, known by his "nom de guerre" of Général Leclerc. On 25 August 1944, Leclerc entered Paris via the Porte d'Orléans with tanks of the 2nd Armored division, on his way to liberate Paris from the German occupation.
