The name of the village was formerly simply 'Condé', which is a place-name widespread in France, deriving possibly from a Gaulish word for a confluence of rivers.
The name is found in the Anglo-Saxon Chronicle for the year 883, reporting that Vikings sailed up the Scheldt to occupy Cundoþ. It is found as Vetus Condatum in the 'cartulaire de Vicogne' of 1215 and as Vies Condet in a work by Jacques de Guise of the 14th century[4]
As the Prince of Condé was a prominent royalist, at the French Revolution the village was renamed 'Vieux-Nord-Libre' until 1810.
