This reknowned church needs no introduction......and it was within blocks of our hotel. It was amazing how many times we viewed it from other locations. The architecture is mind boggling. I was fascinated by those flying buttresses and the beautiful rosette window. (You will see a better photo of the window when I post our photos from the River Seine boat trip.) This is another place that I saw only from the outside. I kept thinking I could return to places.....and this would have been the easiest to return to........but it just seemed as though our time in Paris passed much too quickly. (dreaming of a return trip ").
