Apparently, there was this French architect, Charles Ribart, who added a sense of “fun” in his works, in an age of architectural grandeur.
It is said that he planned an addition to the Champs Elysées, in Paris, where the Arc de Triomphe stands now. It was s’posed to be building on 3 levels, in the shape of an elephant. (I would say that would be an amazing thing to build) It was to consist of a ballroom, with the entry through a spiral staircase from the elephant’s underbelly. The drainage was to be incorporated in the trunk and all the furniture were to be folded into the walls of the elephant when not in use.
But the French government wasn’t amused and called the entire thing off!
