Eiffel Tower Private Apartment By Gustave Eiffel, Champ De Mars, Paris, France

Located on the third level of the tower, Eiffel's private apartment was not large, but it was cozy. In contrast to the steely industrial girders of the rest of the tower, the apartment was furnished in the simple style dear to scientists. The walls were covered in warm wallpaper and the furniture included soft chintzes, wooden cabinets, and even a grand piano, creating a comfortable atmosphere, perched nearly 300m in the air. Adjacent to the small apartment were some laboratory areas equipped with the experimentation gear of the day.
Once word got out about Eiffel's cozy little nest in the sky, Parisian high society turned simultaneously green with jealousy. Eiffel is said to have received a number of sky high offers to rent out the space even for one night. He declined them all, preferring to use the space for quiet reflection, and to entertain prestigious guests such as Thomas Edison himself who gifted Eiffel one of his newfangled phonograph machines.
Today, after being off limits for years, the apartment is on display for visitors to come and peer into. Much of the furnishings remain the same and there are a couple of rather wan looking mannequins of Eiffel and Edison. For the right type of architectural admirer Eiffel's secret apartment could inspire as much jealousy today as it did when it was built.
