Saturday, French tightrope walker Nathan Paulin performs a show between the Eiffel Tower and Theatre National de Chaillot in Paris.

“It was not as easy as I thought,” he said after completing the 600-meter walk.

He added that this accomplishment came after four years of training and overcoming a fear of heights as a child.

“The motivation is about doing something beautiful and sharing it, and bringing something new to our monuments. It’s about making our monuments alive,” the French adventurer said.
