Sainte-Chapelle is a royal chapel in the Gothic style, within the medieval Palais de la Cité, the residence of the Kings of France until the 14th century, on the Île de la Cité in the River Seine in Paris, France. Construction began sometime after 1238 and the chapel was consecrated on 26 April 1248.

Also in this area are Notre Dame and the Conciergerie, which was part of the former royal palace, the Palais de la Cité, which consisted of the Conciergerie, Palais de Justice, and the Sainte-Chapelle. The Conciergerie is where prisoners like Marie Antoinette were held prior to trial and execution during the French Revolution.
