Acrobat Nathan Paulin is balanced from the Eiffel Tower via a 670 meter long rope connection across the Seine to the tower of the Théâtre National de Chaillot on the other bank.
Saturday's feat was part of events across France on the occasion of National Heritage Day.
The theater's dance troupe organized the sensational action, accompanied by music, which will be repeated on Sunday afternoon.
The starting point at the Eiffel Tower was for professional high-wire hikers at a height of 68 meters.
Then he crossed the Seine to arrive at the tower of the theater at a height of 56 meters.
The Eiffel Tower administration announced that it was the longest high-wire connection in an urban area.
The artist and highline world champion had already overcome the connection on the rope in 2017.
Another high rope specialist completed the breathtaking route for the first time in 1989 to mark the 100th anniversary of the Eiffel Tower.
For Nathan Paulin, a balancing act in Paris at the end of 2019 meant at least as much thrill.
The now 27-year-old crossed a 510-meter-long rope connection between two skyscrapers in Paris at a height of 150 meters.
