Place des Vosges. Where the kids can play.
The beautiful green pool at the Eiffel end of the Place du Trocadero. This might not be the Place, but it is next to it on the way to the Eiffel Tower.
Early evening outside Paris city hall (Hotel de Ville). This shot doesn't show the lovely sudsy water.
Fountain below Sacre Coeur showing the lovely green coloration and assorted tourist droppings. The psychedelic spotting may be the onset of pod formation prior to the invasion of the body snatchers.
