Etymology: comes from Mas d’Adam, the name of the old estate that was located on the site of the current village, which was ceded by the lord of Géorant to the bishop of Viviers to allow him to found the abbey of Mazan. It all begins with the foundation of the Cistercian abbey in the heart of the village. This takes place between 1119 and 1122. At the beginning of the 12th century, canons came to settle on the site of Mas d’Adam (a toponym that would evolve into MAZAN), and were joined by monks from the abbey of Bonnevaux. These religious men built a huge abbey, of which only the remains exist today, which experienced a period of apogee that lasted until the Hundred Years' War. It gave birth to four other abbeys which are Bonneval, Sénanque, Sylvanès and le Thoronet as well as establishments for nuns. After this prosperous period, misfortunes followed one another at the abbey of Mazan: it was plundered by the great companies of the Hundred Years' War, then attacked by the Huguenots in the modern period. Before this last looting, the monks, according to legend, would have melted a golden bell with all their treasures, which they would have buried somewhere, facing and opposite the bull's-eye window, within earshot of the rooster's crow. montagnedardeche.com/patrimoine-culturel/village-de-mazan-labbaye-2387

Stroll around the lake on Sunday July 23, 2023. Very pleasant because it is largely shaded. Provide credit card (no possibility to pay in cash) for paid parking from 01/06 to 30/09, package 3€. Lots of people on the beaches and around.
