Climbing Walls. 1987, the Rock Master competition gives rise to the idea of the first artificial walls. A climber suddenly slips on the rock that comes off, distorting the first races. We need a more stable, safer and identical competition ground for all climbers competing. Climbing must adapt and become a real sport, fair and safe for athletes and at the same time visible by a large number of spectators without having to challenge the unpredictability of the mountain: artificial walls and dedicated stadiums are needed. This is how the first artificial climbing walls were born, the playground pre-cut today by thousands of climbers who have never even touched the rock. Yes, this too is a fundamental sparkling moment for this sport. The protagonists tell us the story, as always. Enjoy listening.
