For my best anecdote I have, unfortunately, no pictures!
I was just too physically devastated by the time I caught on.
I got off the metro at the Louvre, then went to the surface to try to figure out where this little art museum was that I wanted to go to. Starting off from the pyramid replicas of glass that mark the Louvre entrance, I headed north. Luckily for me I grabbed an ice cream cone and bottle of water at the only vendor to be seen.
I then headed towards the Egyptian obelisk at the next circle.It wasn't long before my ice cream was gone and the heat started to get to me. I suddenly realized that I was walking on a huge sandy path completely exposed to the elements. Off to my left and right quite a ways were shaded, tree-lined walkways with enches. But out where I was, in the most direct path between these two monuments, the obelisk and pyramids, I was caught under an oppressive sun, shuffling in the sand.
Yes, that's right. In the middle of Paris, some urban planner thought it would be witty to build a desert! If my memory serves me correctly, there is a fountain about half way between them... so, he even put in an oasis.
