In the Palais de Justice on the Ile de la Cit, Sainte-Chapelle is considered a rare jewel of the Middle Ages. This masterpiece of High Gothic architecture was built from 1242 to 1248 for King Louis IX (Saint Louis) to house the precious Christian relics, which he had acquired from the Byzantine Emperor. The altar displays a relic of the Crown of Thorns. The chapel is renowned for its exquisite stained-glass windows, which give the sanctuary an iridescent glow and serene aura.

The colors and light symbolize divinity and the Heavenly Jerusalem. Sainte-Chapelle is rarely used for mass but often serves as a venue for concerts. Listening to classical music in this space is truly an inspiring spiritual experience. To find the chapel, enter the iron gate of the Palais de Justice and walk through the inner courtyard.
