Sainte Chapelle (holy chapel) is one of the only surviving buildings of the Capetian royal palace in the heart of Paris, France. It was commissioned by King Louis IX to house his collection of relics, including the Crown of Thorns which is one of the most important relics in medieval Christendom. See here that some time after 1239 and consecrated on the 26th of April 1248, the Sainte-Chapelle is considered among the highest achievements of the Rayonnant period of Gothic Architecture.
