Chapelle de l'Hôtel d'Harcourt, à l'angle des rues Coupe-Gueule et des Maçons-Sorbonne

The Hôtel d'Harcourt dates back to the Middle Ages, and was the property of various private owners. It was partially demolished in the seventeenth century, leaving behind the ruins of its chapel, later to be demolished in 1852.
