Silence (also Project Hard), is a 45-metre (148 ft) severely overhanging sport climbing route in the granite Hanshelleren Cave, in Flatanger, Norway. When Czech climber Adam Ondra made the first free ascent on 3 September 2017, it became the first rock climb in the world to have a proposed climbing grade of 9c (5.15d), and it is an important route in rock climbing history. To complete the route, Ondra undertook specialist physical and mental training to overcome its severely overhanging terrain. As of October 2024^[update], Silence remains unrepeated.^[2]
