Gémenos (pronounced as /fr/;[2] [3] oc|Gèmas) is a commune located 20 kilometers east of Marseille in the Bouches-du-Rhône department in the Provence-Alpes-Côte d'Azur region in southern France.
A property abstract belonging to Wilhem, Count of Marseilles, dating back to February 9 934, noted for the first time the existence of a castrum named Geminas at the entry of the Saint Pons valley.
In 1204, the bishop of Marseilles Rainier founded the Cistercian abbey of Saint Pons.
Around the 15th century, Geminas was deserted.
In 1563 the Marquis d'Albertas Nicolas and his brother Gaspard, both of Italian origin, acquired the demesne of Gémenos, leading to the development of Gémenos as it is known today.
