Soaring 360 meters into the sky, the Trbovlje Power Station in Slovenia is home to Europe's tallest chimney.
Just the mere sight of it is enough to make most tremble at the knees but two Slovenian climbers saw it as a chance of a lifetime.
In October 2020, Janja Garnbret and Domen Škofic became the first people to free climb the chimney's new route which is now the tallest artificial multi-pitch route in the world.
The pair, who had just a rope to catch them if they fell, were successful on their second attempt after over seven hours of climbing.
"It's definitely the most special thing I've done in my climbing career. It is climbing, but it's a combination of just about everything I experienced before, just combined in one thing,"
Škofic, 26, was a climbing prodigy and won the Lead Climbing World Cup title in 2016; Garnbret is quite simply one of the most talented sport climbers on the planet.
The 21-year-old has won multiple world championships and World Cup titles and is one of the favorites to win gold when climbing eventually makes its debut at the Tokyo Olympics.
Despite their expertize, the challenge was still way out of their comfort zone, with both more accustomed to indoor climbing where the wall is usually no more than 30 meters high.
This route, however, contained 13 pitches (or sections) and involved rope techniques that are very different from what they are normally used to.
The chimney itself was built in 1976 and used to emit emissions out of the valley where it's situated. It's been nonoperational since 2014.
