French climber Alain Robert is known as "Spiderman" for his daredevil ascents of the world's tallest buildings. In his latest attempt, he was saved by safety ropes as he tired to scale the glassy surface of Turkey's highest building.

French climber Alain Robert, known as "Spiderman" for his daredevil rope-less ascents of the world's highest skyscrapers, scaled Turkey's tallest building in Istanbul on Tuesday.

Robert is widely known for illegally climbing skyscrapers but this time he was invited to scale Sapphire, a recently completed building with a height of 261 meters.

Sporting a pair of orange trousers, Robert was full of energy when he began using ropes and a harness but as he came closer to the top he faced an unexpected hurdle.

[Alain Robert, "Spiderman" French Climber]:
"On the last 15 meters of the building unfortunately there is some grease, there is some oil inside the groove, that becomes impossible to jam the right foot."

Despite slippery glass surface the 49 year old climber scaled Turkey's highest building in an hour and 50 minutes.

Robert has climbed more than 80 of the world's tallest structures, including the Eiffel Tower in Paris, Malaysia's Petronas Towers, and the 88-story Jin Mao Tower in Shanghai.

He recently scaled Dubai's Burj Khalifa, the highest building in the world.
