SEOUL, April 12 (UPI) -- Two Russian photographers climbed to the top of the sixth tallest building in the world in South Korea.
Vadim Makhorov and Vitaliy Raskalov of Ontheroofs photography say they decided to scale the 1,823-foot-tall building when they learned that construction cranes were still positioned alongside it.
"The main goal of our trip was a tower, and when we had arrived in Seoul we have been ready to climb to more than hundred floors," they wrote.
The Lotte World Tower has been under construction since 2011. Its 123rd floor was added in December 2015 and external construction completed in March 2016. It is now the sixth tallest building in the world.
The pair decided to share a video chronicling the process of how they managed to scale the massive structure after posting a photo from the building's pinnacle.
"After the publication of a photo from the top of this building in Instagram, a lot of people began to ask us about our managing of the way to inside, because there were tens of perimeters, fighting drones, clusters of chambers on columns and vigilant employees with guard dogs there," they wrote in the video description.
Despite the obstacles, the climbers managed to safely scale and descend the building without being detected.
"At first we thought that we had no chance to wrap that system around our fingers ... But in any one, even in ideal, there are gaps," they wrote.
