Until the 1960s, Citroën's biggest factory stood in the centre of Paris. With a large factory in the heart of a big metropolis, Citroën foresaw logistical problems. An alternative site was found in Aulnay-sous-Bois, a stone's throw from the new Charles de Gaulle airport. Here a huge industrial complex was built that, when it opened in 1973, was the most modern car factory in the world. The last DSs were assembled in Aulnay and, of course, the factory was also the birthplace of the legendary Citroën CX.

In his book, author Julius Goldmann describes the factory in all its facets: the construction and opening, the secrets of the productionlines and all the models that were produced, the strikes, the closure and demolition of the buildings. Memories and anecdotes from former employees and many previously unpublished photos complete the story. A fascinating book about an underexposed part of Citroën's history.
