There has been a monastic community there since the 5th century. The construction of the current monastery buildings began around 1073. Today the monks cultivate vineyards and produce wine and liqueur.
The island, known to the Romans as Lerina, was uninhabited until Saint Honoratus, a disciple of a local hermit named Caprasius of Lérins, founded a monastery on it at some time around the year 410. According to tradition, Honoratus made his home on the island intending to live as a hermit, but found himself joined by disciples who formed a monastic community around him. This had become "an immense monastery" by 427, according to the contemporary writings of John Cassian. In 426 St. Maximus was elected Abbot and remained for seven years until he was appointed the first documented leader of the Ancient Diocese of Riez. The second Abbot increased the renown of the cloister by his miracles and sanctity. There is also a tradition that Saint Patrick, patron saint of Ireland, studied here in the fifth century, and during the sixth century, Saint Quinidius was a monk at Lérins.
One of the Church's most famous authors Vincent of Lérins dwelt in this monastery in the 5th century.
Saint Nazarius (Abbot) (Saint Nazaire), the fourteenth abbot of Lérins, probably during the reign of the Merovingian Clotaire II (584-629), successfully attacked the remnants of paganism on the southern coast of France, overthrew a sanctuary of Venus near Cannes, and founded on its site a convent for women, which was destroyed by the Saracens in the eighth century.
Over the following centuries, monastic life on the island was interrupted on several occasions by raids, mostly attributable to Saracens. Around 732, many of the community, including the abbot, Saint Porcarius, were massacred on the island by invaders. It is said that many of the monks escaped, because Porcarius had been warned of the attack by an angel and had sent them to safety.
After about 300 years, a fortified monastery was built between the eleventh and fourteenth centuries.
The monastery continued to suffer from Spanish and Genoese attacks. The number of monks dwindled to four and, in the pre-revolutionary climate of the time, the monastery was disestablished in 1787. In the French Revolution, the island became the property of the state, and was sold to a wealthy actress, Mademoiselle de Sainval, who lived there for twenty years.
