A small cathedral chapel on the territory of the Royal Palace. It was originally created to store holy relics that were exported during the Crusades. We were delighted with the beautiful stained glass windows describing various scenes from the Bible. It's insanely beautiful. The chapel is connected to the palace by a gallery.
One of the most vivid impressions in Paris is Saint Chapelle! It is important to purchase tickets and a time slot online in advance, the number of tickets at the box office is limited, and there is practically no chance of getting inside without a pre-purchased ticket.
