French climber Alain Robert scales the 856 feet high Sapphire Tower in Istanbul on May 17, 2011. The Sapphire Tower is Turkey's highest building.

Alain Robert usually climbs skyscrapers illegally, but this time, he was invited to scale the recently completed building in Istanbul. Robert has climbed more than 70 skyscrapers including the Empire State Building and last March, the world's tallest building, the Burj Khalifa in Dubai. I wonder if it was as scary for the photographer as it looks like it must be for the climber.
