The city of Paris has all to do about art. Once you visit the city you'll get to know why. Art is everywhere -buildings, gardens, statues, light poles, etc.
I "only" had a day to visit it -well, some hours- and if you don't get into museums, you'll be surprised on what you can see by foot in that short time. Again, I say, walking. You can take a bus to see the city but you'll likely see little and remember nothing.
Here is my tribute to this wonderful city. All taken in the day light on an Autumn day.
The bus that would take me an hour south to Paris. It appeared to be a wonderful sunny day down there.
