Beneath the Arc is a WWI tomb for unknown soldiers, whose ghosts probably feel pretty thankful that they weren't forced to spend eternity underneath another of the proposed designs for the monument: a monstrous, water-spewing circus elephant.
At least it's on a slope, so the massive piles of shit would simply slide into a nearby river.
The idea of installing an obnoxiously prodigious pachyderm in the middle of downtown Paris traffic came about as the result of a design competition in 1758. The designer, one Charles Ribart, conceived the L'Elephant Triomphal: Grand Kiosque A La Gloire Du Roi as a three-story, zoomorphic structure where fancy banquets and balls could be held within the belly of the beast, like a chichi version of the rhino scene from Ace Ventura 2. The "Triumphant Elephant" would have been equipped with hi-tech innovations such as air-conditioning, wall-folding furniture, and a drainage system in the trunk, "from which water would gush out into a decorative trough."
"Decorative troughs" having been previously enjoyed only by the wealthiest of French livestock.
