The SS "Île de France" was a French ocean liner that was built in Saint-Nazaire, France, for the Compagnie Générale Transatlantique (or CGT, also known as the "French Line"). The ship was named after the region around Paris known as "L'Ile de France", launched in 1926 and commenced her maiden voyage on June 22, 1927. It was the first major ocean liner built after World War I, and was the first liner ever to be decorated almost entirely with modern designs associated with the Art Deco style. She was neither the largest ship nor the fastest, but was considered the most beautifully decorated ship built by CGT, becoming the favored ship of the pre-World War II era, carrying young, wealthy and fashionable Americans to Europe and back.
