Paris-Place de la Concorde
The Luxor Obelisk-I'm not sure but somewhere around here is where the guillotine was placed during the Reign of Terror. My brief google searches claim that about 1,900 people had their heads removed here.
This fountain is dedicated to french rivers, primarily the Rhone and the Rhine. The fountain at the other end of the Place de la Concorde is meant to represent the oceans.
There are eight statues at the corners of the Place de la Concorde. Apparently, they represent French cities or areas. I don't know know which one this is. This just a case of me being zoom happy.
