Before tackling the ascent of urban buildings, Alain Robert was considered one of the best specialists in the "climbing" of cliffs. His passion nearly cost him his life in 1982, when a fall rendered him 66% disabled. At the time the doctors were convinced that he could no longer indulge in this passion. This does not prevent him, by dint of motivation and training, from climbing more than 170 buildings around the world to date, and from soloing technical routes at his maximum level, such as "La Nuit du Lézard". (8a+) in Buoux (France), where here is "L'Ange en Décomposition", in 1991, a mythical course in the Gorges du Verdon.
