I was told that many people now go to Paris to follow the Da Vinci Code route. Although I am a big fan of the book, I wasn't up for looking for the Holy Grail the last time I was in Paris. What I did see, however, were a number of monuments so pointy that I went back home convinced that Paris is the world's phallic capital.
In the Louvre Museum, one of the phallic curiosities one can see is the Code of Hammurabi.
The Parisians also have this Egyptian obelisk at the center of the city.
Of course, the most famous Parisian phallus is the Eiffel Tower.
