Sainte-Chapelle

The magnificent 13th-century Gothic chapel of Sainte-Chapelle is small in comparison to other Paris churches, but its 6,458 square feet of stained glass in the upper chapel is considered to be the best in the world. What we discovered when we visited was that the lower chapel is quite attractive as well, as you can see in this album.
