The Île Saint-Honorat is the second largest of the Lérins Islands, about a mile off shore from the French Riviera town of Cannes. The island is approximately 1.5 kilometers in length (East to West) and 400 meters wide.
Since the fifth century, the island has been home to a community of monks.
The island, known to the Romans as Lerina, was uninhabited until Saint Honoratus 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 (including Saint Caprais (Caprasius) who formed a monastic community around him. This had become "an immense monastery" by 427, according to the contemporary writings of John Cassian.
The monastery provided three bishops for the See of Arles: Honoratus himself, followed by Hilarius and Cesarius in the fifth and sixth centuries, respectively. Reputedly, Saint Patrick, patron of Ireland, studied at the monastery in the fifth 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. According to myth, many of the monks escaped, because Porcarius had been warned of the attack by an angel and had sent them to safety.
The monastery continued to suffer from Spanish and Genoese attacks. The number of monks dwindled to four and, in the proto-revolutionary climate of the time, the monastery was disestablished in 1787. Under the 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.
In 1859, the island was bought by the Bishop of Fréjus, who sought to re-establish a religious community there. Ten years later, a Cistercian community was established, which has remained there ever since.
The island retains a monastery, which is home to 30 Cistercian monks, and is a popular tourist attraction offering pleasant woodland surroundings, in common with its neighbour the Île Sainte-Marguerite. Points of interest include a number of disused chapels erected by monks on the island at different points in history, as well as the remains of a Napoleonic cannon ball oven and a Second World War gun emplacement.
The Abbey of Lérins and the 15th Century fortified monastery are open to visitors, and a monastery shop sells various monastic goods, including wine and honey produced on the island. The modern monastery is closed to visitors, although it is used as a Christian retreat.
