Sainte Chapelle - Paris

It's not always the easiest monument to find, but it is one of the greatest. Visiting a 13th century chapel is an amazing experience. If you remember your gospel, the images in the glass will make more sense, but you can still enjoy the beauty of this room as you visually inhale the rich light and textures of this amazing building. It's much smaller than Notre Dame, but much finer in details.
