Just about everywhere you look the architecture and detail is great. When you enter the area where the chapel is you expect to be seeing much more than you actually see, but what you do see is pretty cool.
It was wonderful that we had skip the line tickets. We were able to walk right in while there was a very long line of others wanting in standing in the sun. This is not a guided tour but a look on your own. There are informational cards in a variety of languages available to view or audio tours for purchase. The stained glass is amazing.
