Mr Robert scaled the building as part of a climate change protest
French urban climber Alain Robert has scaled the Lloyd's of London building in the City as he joined the protest over climate change.
Mr Robert climbed the famous building at One Limehouse Street and unfurled a 100-foot banner that warned of "100 months" left to save the planet.
Witnesses said Mr Robert did not use ropes as he climbed up to the ninth floor of the 290-ft building.
He was met by police as he descended from his climb.
A spokesman for insurer Lloyd's of London said: "He climbed to the 9th floor of the building and then unfurled a banner.
"Then he folded it up and climbed down. He was only up there for about 20 minutes."
Mr Robert, known as the 'human spider', has conquered some of the tallest and most famous buildings in the world, including Sydney Opera House, Petronas Towers in Kuala Lumpur, and Canary Wharf in London's Docklands.
In 2008, he climbed the New York Times Building in New York City to protest about climate change and was arrested by police on the roof.
His latest stunt saw him return to the Lloyd's building which he last scaled in May 2003 in a publicity stunt to promote the Spiderman film.
