A bit of history

Moulins de Villancourt

Cosmocité is built on the site of an old water mill called “Les Grand Moulins de Villancourt”. The mill produced flour for the Brun biscuit factory and has marked the industrial and social history of Pont-de-Claix since 1869. Designed by the architects Arcane and Cardin-Julien, the white volumes of Cosmocité echo the shape of the original mill building, dismantled in 2019.

Accessible free of charge in the lobby of Cosmocité, the ‘memorial testimonies’ tell the story of the place.
