Urban climber Alain Robert, known as "the French Spiderman", has scaled his country's tallest building.

Having climbed more than 100 skyscrapers and monuments across the world, Robert set his sights on the 231-metre (758-feet) First Tower at La Defence district in Courbevoie on the outskirts of Paris.

Office workers gazed out of their windows in disbelief as the 49-year-old went past on his way to the top, using only his bare hands and climbing shoes.

After a brief stop at the 21st floor, Robert ascended the remaining 29 storeys to add another building to his death-defying achievements.

The Frenchman's previous conquests include New York's Empire State building, the Sydney Opera House and the Petronas Twin Towers in Kuala Lumpur.

Robert has often been arrested after reaching the summit of some of the world's most iconic structures.

But this time there were no police to greet him, as he was granted prior clearance to climb from the skyscraper's owner.
