The Sainte Chapelle (Holy Chapel) is on the island of the Ile de la Cité in the center of Paris.
In the beginning of the 13th century during the Crusades, the Emperor Beaudouin II de Courtenay had such a huge need for money that he was willing to sell the most important relic that he had: the Crown of Thorns. He met with King Louis IX and, after two years of discussions to confirm the authenticity of the relics, the holy Crown arrived in France in 1239.
Two years after that, the King of France acquired other relics of the Passion, of which there is a part of the holy Cross. Louis IX decided to build a monument worthy to house the relics: the Sainte Chapelle was built in the center of the royal palace on the Ile de la Cité.
This master-piece was built in 5 years. The lower part has an openwork design and is painted, high in color. The upper part is flooded with light with huge stained glass windows. There is nothing to compare it to! This chapel is an architectural feat and remains a royal showcase that held the holy relics.
Visitors are stunned by the beauty of the upper part. The relics are no longer in the Sainte Chapelle though they may be venerated by pilgrims today at the Cathedral of Notre Dame de Paris on certain Fridays.
