Ile de la Cite in Paris has more to offer than just Notre Dame Cathedral. Sainte Chapelle is a jewel of Gothic art built during the 12th century for King Saint Louis. It was originally built to house the Crown of Thorns of Christ which is now stored at Notre Dame. The chapel is covered with 600 square meters of stained glass windows. It’s one of the most magnificent stained glass displays in the world. The architecture and stained glass windows represent a major example of the Gothic period. The stained glass shows more than 1000 scenes from the Old and New Testaments. The Chapel of Sainte Chapelle is a UNESCO World Heritage site.
