The Porte d'Orléans is one of 17 portes (city gates of Paris) in the Thiers wall, a defensive wall constructed in the mid-nineteenth century to protect Paris. The wall was demolished after the First World War, creating an open space that was subsequently built up. The Porte d'Orléans is now one of the main gateways to the capital, and is located in the 14th arrondissement of Paris.
Porte d'Orléans is located around the Place du 25-Aug-1944, at the crossroads to the north of the Avenue du General Leclerc, the Boulevard Brune, and Boulevard Jourdan, and to the south of the intersection of Avenue de la Porte d'Orléans, the Avenue Ernest-Reyer, the Avenue Paul Appell and Rue de la Légion-Étrangère.
The Porte d'Orléans owes its name to the fact that the road coming from Orleans, known today as Route nationale 20, led there. This axis was of great importance to the Middle Ages to the cohesion of the emerging monarchy as Paris and Orleans were then the two main cities of the royal domain.
It was through the Porte d'Orléans that elements of General Philippe Leclerc de Hauteclocque's 2e Division Blindée (French 2nd Armored Division) became the first Allied units to enter the capital, on 24 August 1944, thus contributing to the liberation of Paris during World War II. This event was an important step in realizing the oath that Leclerc had done before his men after the Battle of Kufra in 1941, that he would not lay down his arms until the French flag flew once again from the Strasbourg Cathedral. The Oath-of-Kufra Square, situated on the west side of the Porte d'Orléans between the Avenue de la Porte d'Orléans and Rue de la Légion Étrangère commemorates this episode.
