Lotte World Tower climb

Russian climbing duo Vitaliy Raskalov and Vadim Makhorov, members of the aptly-named collective On the Roofs, reached new heights this week, scaling South Korea’s tallest skyscraper, The Lotte World Tower.

Raskalov and Makhorov traveled to Seoul, South Korea, specifically to try and climb the tower, which is still under construction. They managed to elude guards and other security measures on the way to the summit, as part of the global trend of “roof topping,” a brazen hobby that combines trespassing, dizzying heights, free climbing, and photography and has resulted in deaths, arrests, and banishment.

Raskalov and Makhorov were not deterred by the building’s security measures, though, and made it to the top of the tower, documenting their journey all the while on Instagram, their website, and in the video above.

The dizzying feat is nothing new for the climbers. In May 2015, they climbed China’s 115-story Shenzhen Center, one of the tallest buildings in the world, second only to the Burj Khalifa in Dubai. The fearless duo has also climbed China’s Shanghai Tower, which seemingly inspired a German tourist to climb Shanghai’s Jin Mao Tower, a venture that ended with him getting arrested.
