Probably built in the 11th century, on an older base, this rural chapel is a good example of early Romanesque art in Provence. The building, which was extensively reconstructed from the 17th century onwards, consists of two levels.
The upper church originally had a main apse and two smaller apsidioles opening onto a central nave and two side aisles with two bays. The western bay no longer exists. The crypt was also arranged in a three-sided plan. However, all that remains today are two small central naves ending in vaulted apses and a side niche to the south, as the nave to the north has collapsed.
The sculptures in the crypt bear witness to a decorative expression at the crossroads of several influences: Roman tradition, Provençal Romanesque art and Byzantine art. The columns are decorated with palmettes motifs and twists, while the capitals, or column caps, are decorated with interlacing, plant motifs and animal representations: ram heads, peacocks, etc.
The "triconque" plan, or three-sided plan, of the crypt has long led to the belief that this chapel could be a martyrium (burial place of a martyr), but it could also simply be a place used for the conservation of relics, perhaps those of Saint Geniès, which were transferred from Arles in the 11th century by the Saint Victor of Marseille Benedictine monks.
