The Collège Pasteur in Caen has a history that we feel is important to share. It explains its configuration and preserved architecture. The college symbolizes the separation of Church and State at the beginning of the 20th century, it retains the stigma of the Second World War, its transformations also reflect the evolution of the education system. It is regularly observed and photographed outdoors for its «Arts Deco» facade and is part of the heritage of the city of Caen. Participating in heritage days is a way to discover it indoors and reveal its «secrets». Place usually closed to the public.
