The Frioul Islands and the Chateau d’If

The islands of the Frioul number four: Pomègues, Ratonneau, If and Tiboulen. Their "calanques" become wilder as one moves away from the landing port: Port Frioul.
The Chateau d'If is a fortress set on the If island. Created under François 1st and completed in 1531 it soon became a prison for mutiny galley slaves and later many protestants in the 17th Century, the 1848 insurgents and the "Communards" of 1871.
Alexandre Dumas' Count of Monte Cristo immortalized the Frioul.
