Established at 260 m above sea level on the immediate outskirts of the creek of Luc, about 800 meters west of its confluence with the river Aude, the village clusters its houses on the southern flank of a small limestone greenhouse. The site of Luc sur Aude has been known since the Gallo-Roman period. The ancient habitat is essentially agglomerated around the old village with the notable exception of two buildings: the metairie of Luc and the gentleman’s residence of Castillou. Most of the agricultural activity is therefore concentrated in the lower parts of the territory, where the sheltered soulanes and hillsides host a vineyard producing quality white grape varieties, such as chardonnay.
