Ste Marguerite

Ste-Marguerite, 3km/2mi long and up to 1km/0.5mi wide, is the largest island of the Lérins group and is covered with eucalyptus and pine woods. On its northern side stands a 17th C fort, fortified by Vauban, which served for a long time as a prison. Towards the end of the 17th C the man known as the "Masque de Fer" (Man in the Iron Mask), who was surrounded in secrecy and whose identity has never been established, was held prisoner here.
