La Sainte-Chapelle (English: The Holy Chapel) is a Gothic chapel on the Île de la Cité in the heart of Paris, France. It is perhaps the high point of the full tide of the rayonnante period of Gothic architecture. It is famous for housing Christian relics including the crown of thorns brought to the site by Louis IX.
