Origin and history
The islands of Lérins, located in the Mediterranean opposite Cannes in the Alpes-Maritimes, form an archipelago composed of two main islands, Sainte-Marguerite and Saint-Honorat, accompanied by three islands. Sainte-Marguerite, the largest, is famous for its royal fort built in the seventeenth century, where the Man was imprisoned with an iron mask. Saint-Honorat, smaller, houses a monastery founded in the fifth century by Saint Honorat, a major figure of Western monasticism. The archipelago, inhabited since ancient times, bears the traces of a Roman city, an oppidum ligure, and a Greek legend linked to the cult of the heroes Lêron and Lérinê.
The history of the islands is marked by natural disasters, such as the earthquake of 410 which overwhelmed some of the ancient remains and drained the freshwater springs. In the Middle Ages, the monastery of Lérins became a spiritual and intellectual center, forming bishops and missionaries like St Patrick. The Saracen raids and modern conflicts, including the Spanish and English occupations, have left traces in the fortifications of the archipelago, such as the royal fort rebuilt by Vauban.
In the 19th century, the islands were used as a state prison, welcoming figures such as Marshal Bazaine or Bishop Maurice de Broglie, who introduced eucalyptus. Today, the archipelago combines historical heritage, with classified museums and remains, and environmental preservation, through strict measures to protect its marine and terrestrial biodiversity. Classified as a Natura 2000 area, the islands are home to unique Mediterranean ecosystems, such as Posidonia grass beds and coral reefs, while remaining a major tourist destination on the French Riviera.
The Lérins Monastery, which is still active, is known for its production of wine and liqueurs, while the Royal Fort houses the Museum of the Sea, exhibiting collections of underwater archaeology. In 2021, an underwater ecomuseum was installed, with sculptures promoting the regeneration of the seabed. The archipelago, a UNESCO World Heritage candidate, embodies a balance between history, spirituality and ecology.
The topography of the islands reveals a natural symmetry: Sainte-Marguerite and Saint-Honorat, separated by a canal, are surrounded by deserted islands. Their unaccidental relief culminates at 26 meters at the Royal Fort. Sainte-Marguerite, covered with pines and eucalyptus, has a central pond and hiking trails, while Saint-Honorat, dedicated to monastic life, is dotted with chapels and vineyards. The 18th-century pellet furnaces, designed to heat projectiles, testify to its strategic role.
Current regulations limit the speed of vessels and prohibit jet skis near the coast to preserve fragile ecosystems. The islands, accessible by shuttle from Cannes, attract visitors for their heritage, landscapes and tranquility, while highlighting eco-responsible tourism.
