The Collegiate Church of Notre-Dame de Mantes-la-Jolie is a former collegiate church from the 12th and 13th centuries located in Mantes-la-Jolie (Yvelines, France) on the banks of the Seine. It was classified as a Historic Monument in 1840. This church is reminiscent of Notre-Dame Cathedral in Paris in style and in its elevation on three levels.

A Bridge With strange colossi...!

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.
