Saint Chapelle is truly one of Paris's gems. The stained glass is just stunning. The secret to enjoying St. Chapelle is to visit it on a sunny day; when the rays of sun can shine through the panes. I have been fortunate to have been able to visit it on many occasions. I must say I have never been disappointed. On my last visit to the chapel I went to a concert. The nighttime experience is completely different from seeing the chapel during the day. If you have never been during the day I would not suggest only going at night.
