Fireworks celebrate the opening of Lotte World Tower in Seoul on April 2, 2017.
The cloud-piercing skyscraper is currently the 5th tallest tower in the world.
Designed by Kohn Pedersen Fox Associates, the tower has a tapered shape that's inspired by Korean art and cultural aesthetics.
The Sky Shuttle double-decker elevator set two new records for being the tallest and fastest of its kind.
The elevator zips guests from the basement to the observation deck on the 121st floor in 60 seconds, or at a speed of 10 meters per second.
Inside the lift cabins, it feels like a video game -- 15 OLED displays present a virtual tour of Seoul during the 60-second ride.
Made by American elevator manufacturer Otis, the lift comprises two attached cabins stacked on top of each other, simultaneously carrying 54 passengers in each cabin.
The expansive view overlooks the Seoul cityscape and Cheonggyecheon River, which flows through the heart of the city.
From the top, visitors can see all of Seoul and as far as the Yellow Sea, to the west of South Korea's capital. If not for the mountains in the distance, North Korea would be visible on a clear day.
Lotte World Tower took six years to construct. It houses 61 elevators and 123 floors containing shopping complexes, offices, and even a "seven star" hotel.
The view from Lotte World Tower, stretches 50 kilometers in every direction.
