Somewhere close to the Seine river, hidden between the buildings, a strange shape rises from the ground, that looks like an UFO has just landed on Earth. Although it may not seem anything like a cathedral, that's exactly what it is: Cathedral of Créteil extension.
The creator of this unique design is Charles-Gustave Stoskoph. During day time, the window located at the junction of the hulls offers a colored light into the sanctuary. After the sun sets, it is illuminated from the inside and creates a reflection of The Christian Cross.
