The Man in the Iron Mask was imprisoned for 34 years!
 Who was 'The Man in the Iron Mask'? It is undoubtedly the oldest French state secret.

 Louvois, minister of Louis XIV, sends him in July 1669 to the Prison of Pignerol, a small French locality in Northern Italy. The masked man joins two infamous courtiers: Nicolas Fouquet and the Comte de Lauzun. But what crime could this subject of Louis XIV have committed to remain alive yet imprisoned until 1703?
