The Armenian community of Alfortville is very significant. The Armenian Apostolic Church, located south of the city, is an important place for the Armenian community. There are streets named after Komitas Vartabed, Missak Manouchian, and the city of Yerevan. A roundabout has recently been named Place d'Achtarak after the Armenian city Ashtarak.
After military clashes in the Armenian-populated breakaway Nagorno-Karabakh region between Armenian and Azerbaijani troops resumed in 2020, the city council of Alfortville unanimously voted to support the recognition of its independence under its Armenian name of Artsakh Republic,[5] making it the first French city to do so.
