You probably know the story that French writer Guy de Maupassant hated the Eiffel Tower but regularly dined in its restaurant, saying it was the only place where he couldn’t see the tower. Few people know, however, that there’s a real apartment at the very top of the Eiffel Tower.

Gustave Eiffel, the architect behind the Paris landmark, couldn’t resist the small indulgence of having an office 300 meters up. During construction he fitted a small apartment on the tower’s upper floors with two bedrooms, a living room, a kitchen, a bathroom, and a laboratory.

He mostly used it to relax and entertain guests; once he spent ten hours there talking with Thomas Edison.

Today the apartment is open to tourists. Visitors are greeted by wax figures of Edison and Eiffel recreating their meeting on September 10, 1899. What are the two men discussing? The achievements of technological progress!
