The extreme climber known to some as Spiderman has struck again - this time, on France's new tallest building.
Alain Robert scaled the recently heightened First Tower in the La Defense business district west of Paris.
Hundreds of onlookers peered out of its windows or craned their necks as he went up.
The Frenchman has ascended more than 100 skyscrapers and monuments over his 15-year career of daredevil climbs using no support equipment.
Often his climbs are illegal, but not this time - his latest feat up the 758ft (231m) building was given the go-ahead by its owner.
Robert said he does not battle fear on the way up because "I really don't have time to be afraid, I really have other things to do."
