The Beauvais Cathedral, one hour north of Paris, strikes the eye by its whiteness and its grand architecture. Work began in 1225 with the bishop wanting to create a monument that would be the most majestic in Christianity. His ambition was so huge that he was unable to finish the construction project. In spite of not being completed, the cathedral today is a magnificent sight. It is full of light thanks to the whiteness of the chalk stone, as well as to the height of the vaulting and of the choir. Inside are two clocks: an astronomic one and one with chimes. This second one is supposed to be the oldest one in working order today. The Association of Beauvais Cathedral regularly puts on Sound and Light shows through which one can discover in a grand way the architecture of this beautiful edifice.
