Several dozen kilometers from the center of Paris, the Notre-Dame de Mantes-la-Jolie collegiate church does not only have its name in common with the emblematic Parisian cathedral. Its facade, its style and its structure on three levels are very reminiscent of its big sister in the Ile-de-France region.
