Chateau d'If, although most famous as the prison where Edmond Dantes was incarcerated in Dumas' "the Count of Monte Cristo," did serve for more than a century as the most feared prison in France, which makes its record of notoriety significantly greater than Alcatraz, whose life as a federal prison lasted less than 50 years.
It looks so harmless cause of the pasty white look to it. Crazy to think of all the things that probably happened there.
No kidding. It's hard to believe that incarceration on a Mediterranean island could really be that bad. (^_^)
That's one sold fort!
