Chartres Cathedral has a majority of its original medieval stained glass windows.
 All three of these windows were originally made around 1145 but were restored in the early 13th century and again in the 19th
Long renowned as "one of the most beautiful and historically signifcant cathedrals in all of Europe," it was designated a World Heritage Site by UNESCO in 1979, which called it "the high point of French Gothic art" and a "masterpiece"
