Sainte Chapelle is a small cathedral that ispatterned after Chartres in terms of its stain glass. It is situated in Paris on the Ile de la Cite in front of Notre Dame cathedral. It was originally built by Louis IX in around 1239 AD and was heavily damaged during the French revolution because it was a symbol of the French monarchy. Chartres of course it massive, Sainte Chapelle is tiny, but intense.
The amount of stained glass for the size of the building is incredible. Unfortunately, Sainte Chapelle is dead. It is no long a living place of worship. It is just a museum of gothic style architecture and stained glass, a very good museum indeed. The best thing about this cathedral is that is shows color inside similar to what was once inside of Chartres. It is spectacular.
