The Fort Eve is located on a 3-hectare limestone island about 1 mile from Marseille's old port. It is a 28-meter square building with three cylindrical towers with wide shooting holes on the walls. The Fort ve was originally proposed by King Francis I of France to strengthen the defences of Marseille, and was completed in 1531 and used as a prison shortly after its completion. In 1844, the French literary magnate Dumas completed the creation of the Count of Monte Cristo in the context of the Fort Everett, the hero of the framed and imprisoned, and this prison is the famous Fort Everett.
