Lately two photographers,Vitaly RaskalovandAlexander Remnev, have been generating a lot of buzz around this subject.
Alexander Remnev himself is only 18 years old.
Every climb is done without a harness so it is important to keep a cool head.
His biggest challenge, he said, was a building with 74 floors - a staggering 900ft tall.
He explained: I got involved with this because I’ve always liked to take pictures from above.
I wanted to know the unknown and conquer the unconquered.
I love to watch from above as the sun sets.
