The Orge ({{IPA|fr|ɔʁʒ|-|LL-Q150 (fra)-GrandCelinien-orge.wav}}) is a {{convert|54.1|km|mi|adj=on}} long river in France, left tributary of the Seine.{{sandre|id=F46-0400|nom=L'Orge}} Its source is in the village Saint-Martin-de-Bréthencourt. Its course crosses the départements of Yvelines and Essonne. It flows northwest through the towns of Dourdan, Saint-Chéron, Breuillet, Arpajon, Savigny-sur-Orge, and Viry-Châtillon, finally flowing into the Seine in Athis-Mons, south of Paris. The towns located on the banks of the river usually have s/ Orge added to their name (i.e. Épinay-sur-Orge, Longpont-sur-Orge, Villiers-sur-Orge). The Yvette is a tributary of the Orge.
Promenade de l'Orge
Many of the local councils maintain parks on the banks of the river. A syndicat has been formed to link the parks of 32 communes.[http://voiescyclables.free.fr/download/promenadeOrge.pdf Paths of the Promenade de l'Orge] The result is a footpath that ends in Athis-Mons, where the Orge flows into the Seine. Bicycles are allowed on the footpath although pedestrians have right of way. Motorised vehicles are not allowed.
Port-Aviation
In May 1909 a venue for aviation races and exhibitions, Port-Aviation, opened to the public in Viry-Châtillon as the world's first purpose-built aerodrome. The airfield, often referred to by the misnomers "Juvisy Airfield" or "Juvisy" due to its proximity to Juvisy-sur-Orge, was located at a point where the Orge forked into two branches, one of which ran along Port-Aviation's northwestern perimeter and the other across the northwestern, northern, and northeastern portions of the airfield itself. Flooding of the Orge that began in mid-January 1910 forced the closure of Port-Aviation and the evacuation of its hangars until March 1910. Although Port-Aviation operated as a civilian aviation venue until 1914 and as a military aviation training site during World War I, it closed and was abandoned during 1918 in part because it was prone to flooding by the Orge. A housing district also named Port-Aviation was constructed on the site of the former airfield between 1919 and 1933 and also suffered from flooding until 1932, when the Orge was canalized in the area and a pumping station was installed.{{cite web |author= |date=29 December 2013 |title=Port-Aviation |url=https://www.forgottenairfields.com/airfield-port-aviation-1179.html |website=Forgotten Airfields of Europe |location= |publisher= |access-date=6 June 2025}}[http://www.tourdeparis.co/port-aviation-premier-aerodrome-monde/ tourdeparis.co port-aviation-premier-aerodrome-monde (in French)].{{cite web |author= |date= |title=Port-Aviation - the world's first purpose-built airfield |url=https://www.thefirstairraces.net/meetings/po0910/venue.php |website=The First Air Races |location= |publisher= |access-date=4 June 2025}}{{cite web |author= |date= |title=After floods and bankruptcy, the revival of the world's first airfield |url=https://www.thefirstairraces.net/meetings/po1006/events.php |website=The First Air Races |location= |publisher= |access-date=4 June 2025}}{{cite book |author= |date=March 2024 |title=Port-Aviation: Premier aérodrome organisé au monde |trans-title=Port Aviation: First Organized Aerodrome in the World|url=https://viry-chatillon.fr/app/uploads/2024/03/portaviation.pdf |location=Viry-Châtillon, France |publisher=Ville de Viry-Châtillon |page=35|language=fr|access-date=23 May 2025}}
