Discover a gem of Gothic style built in seven years: The Sainte Chapelle in the Palais de la Cité! Consecrated on 26 April 1248, the Sainte-Chapelle is considered among the highest achievements of the Rayonnant period of Gothic architecture. It was commissioned by King Louis IX of France to house his precious collection of Christian relics, including Christ's crown of thorns, acquired by Saint Louis. Along with the Conciergerie, the Sainte-Chapelle is one of the earliest surviving buildings of the Capetian royal palace on the Île de la Cité. Although damaged during the French Revolution, and restored in the 19th century, it has one of the most extensive 13th-century stained glass collection anywhere in the world. Arranged across 15 windows, each 15 meters high, the stained glass panes depict 1,113 scenes from the Old and New Testaments recounting the history of the world until the arrival of the relics in Paris.
