A flamboyant church made up of the double Ambulatory of the choir, which the ceiling with the multiple mouldings descending onto columns has led to be compared to a palm grove. Beautiful stained glass windows from the late 15C and modern windows of many colours by lighting up the chapels of the apse. Dear to lovers of the old Paris, this church is surrounded by a little garden following the location of the ossuaries of which some galleries still survive.
