According to legend, the islands of Sainte-Marguerite and Saint-Honorat were named after Honorat d'Arles, founder of the Abbey of Lérins, and his sister Marguerite. The story goes that Marguerite was not allowed to visit her brother on the religious island of Saint-Honorat. Despite this, her brother promised to see her at least once a year, when the almond trees were in bloom. Marguerite, who missed her brother terribly, prayed so hard that an almond tree on the island began to blossom every month.
Another legend has it that Honorat and his sister Marguerite fought a dragon on the island. The dragon was mortally wounded and died in the hills around Draguignan.
