If you are in Paris for any length of time at all, you have GOT to visit this chapel! I can’t really understand why so many people visit Notre Dame when the Sainte Chapelle is a five minute walk away and, to my mind, infinitely more beautiful and impressive. The walls of the upper chapel are almost entirely made of stained glass and it’s just fantastic. As a penniless student I couldn’t afford a ticket to one of the concerts that are held here, but when I go back to Paris that will be top of my list of things to do.
