There are mansions that symbolize France. Surviving for centuries, they gained fame across the world: Versailles, the Louvre, Saint-Germain-en-Laye, Vincennes or Chambord. An unprecedented event changed everything: the Second World War June 1940. The German army occupies Paris. Adolf Hitler, victorious, visits the city. The swastika flag flies over the Eiffel Tower and the Palace of Versailles.
The war turns into an air combat and the castles get in great danger.
Hermann Goering, an art collector at heart, organizes an extensive plunder of works of art to enrich his private collection, threatening
permanently French cultural heritage. Besides, Hitler is determined to create a colossal museum in Linz that would gather the greatest treasures of occupied Europe. The greatest castles and their treasures could have disappeared forever.
How did the French castles face the Nazi invasion? By which covert actions did these stone walls, gildings, precious wood furniture, statues of marble, and majestic staircases escape annihilation? What happened to the most precious masterpieces like the Mona Lisa?
Women and men, involved in underground networks, resisted and saved this heritage.
