While in Paris, one of my very favorite places we saw was San Chappelle. I took hundreds of pictures there. The stained glass was beautiful beyond description. I even took pictures of the ornate tile work on the floor. But I bet few people stop, stare, and take pictures of what I saw outside. There are piles of architectural rubble stacked next to the building. San Chappelle is an incredibly ornate chapel. It appears that over the years pieces have fallen from the structure. There is an iron fence keeping visitors away from the exterior, but I took pictures of the remnants.
I plan to file these pictures away for use as inspiration when I need architectural ideas.
