The Frioul archipelago comprises four islands covering a total area of 500 acres, located around 4 km offshore of Marseille. The islands are considered as one of the city's 111 quarters and are situated in its 1st arrondissement.
The archipelago's largest islands are Ile Pomègues (2.7 km long and 89 metres high) and Ile Ratonneau (2.5 km long and 86 metres high). The remaining islands are Tiboulen and Ile d'If, home to the ancient Château d'If prison. This fortress was the site where Edmond Dantès, the imaginary hero of Alexandre Dumas' "Count of Monte Cristo", was imprisoned.
The emblematic "MIMI" (International Innovative Music Movement) festival, held every summer in the courtyard of the ancient Hôpital Caroline, headlines innovative artists from all musical and geographical horizons, and has now become a European reference. The festival is organized by the "AMI" association (Aid to Innovative Music and National Centre for the Development of Contemporary Music), based at the "Friche la Belle de Mai" in Marseille.
