It was free-climber Alain Robert's second time scaling the Agbar Tower in Barcelona, Spain
This astonishing video shows a world-famous free-climber, known as 'The French Spiderman', scale the side of a 475-foot tall building in just 25 minutes.
Alain Robert, 57, is famous for his free solo climbing, scaling skyscrapers using no climbing equipment except for a small bag of chalk and his climbing shoes.
The daredevil has climbed a whopping 165 buildings without a safety cord, including the 1,000-foot tall Eiffel Tower in Paris, and Dubai's Burj Khalifah, which stands at a whopping 2,700 feet tall.
And on Wednesday, 24/03/20, Alain was spotted scaling the Agbar Tower in Barcelona, Spain, which stands 475-foot tall (144 metres).
It took the Frenchman just 25 minutes to make it up the building and back down again - watched and filmed by his friend and fellow free-climber Adam Lockwood, 18.

Adam said: "I knew Alain was here and was going to climb the Agbar Tower, so I climbed to the top of The Arts Hotel last night [Tues] and slept on the roof to watch him.
"It took him about 25 minutes to go up and back down again. When he got back down he got put in the back of an ambulance, and then driven off in a police car.
"Last time he did this he got escorted out the country. I don't know if that's going to happen again now."
Adam added that he has known Alain for about a year - but that Alain has been free-climbing "all his life".
It was the Frenchman's fourth time climbing the Agbar Tower - having previously scaled the 38-storey building in 2006, 2007, and 2016.Video by: Gabriella Petty
