The traditional Camargue farmhouses are solidly built with cairons (or queiroun), cut stone blocks brought by water from Beaucaire, whose name derives from this industry. The absence of stone in Camargue explains the constant reuse of the materials of Gallo-Roman villas and of abbeys, which erases any vestige or ruin, and, consequently, the persistence of the habitat in fixed points. The Camargue farmhouse is a parallelepipedic house on land with communal rooms on the ground floor and bedrooms and haylofts on the first floor. It is extended in its length by annexes (shed, barn/stable, etc.) sometimes built slightly set back or protruding or even at right angles on one of the sides to form an embryonic courtyard.
