What are you missing when you go to Paris? St.-Étienne-du-Mont, an unassuming medieval/Renaissance church slightly off the beaten path. “Our lone Parisian survivor is in a class unto itself: not just the sole instance in Paris, but one of the few in the world, and a magnificent specimen of carved stone. It impels the eye. Looking at this gigantic wedding cake of a loft, one knows instinctively that one is in Paris.”
