Overview
Castelnau-d'Aude is a small rural commune in the Aude department of the Occitanie region in southern France. The recorded population was 491 inhabitants in 2017. The village and its surrounding territory combine agricultural land, vineyards and residential settlements typical of the historic Languedoc plain. The place-name element "Castelnau" reflects the medieval pattern of settlement — literally a "new castle" in Occitan and southern French toponymy — suggesting origins in the High Middle Ages.
Geography and climate
The commune lies in a lowland area of the Aude department where Mediterranean-influenced weather brings warm, often dry summers and mild winters. The landscape is formed by plains and low hills suited to grape cultivation, market gardening and mixed farming. Local lanes and departmental roads connect Castelnau-d'Aude with nearby villages and service towns in the region.
