The door at 29 Avenue Rapp is not your average door—it's like the botanical garden of doors, dreamed up by Hector Guimard when he was apparently in a full-blown romantic relationship with curves. Constructed in 1901, when Art Nouveau was all the rage, it's a twisty, turny tribute to all things natural, with more swirls than your favorite ice cream.

Jules Claretie of the Comédie-Française must have said, "Make it fancy!" and oh boy, did Guimard deliver. It's like every vine and plant in Paris volunteered to be immortalized in iron. The whole building is a grand high-five to extravagance, with balconies and windows that practically wink at you.

Nowadays, this door is like the celebrity of Art Nouveau architecture in Paris. Tourists flock to it, snapping pics and wondering, "How much does a door like that even cost?" It's a historical runway model, strutting its stuff from the Belle Epoque era right into the hearts of art and architecture fans.
