Sainte-Chapelle

La Sainte-Chapelle is a Gothic chapel in Paris, France, built in 1246 by the very devout king Louis IX of France as a chapel for the royal family and then as a shrine for what is said to be Christ's crown of thorns, taken from Constantinople (Istanbul) during the Crusades. The king was later granted sainthood by the Roman Catholic Church as Saint Louis.

The most visually beautiful aspects of the ancient chapel, and considered the best of their type in the world, are its stained glass and rose windows added to the upper chapel in the 15th century.
