From the top of the half kilometer-tall tower, visitors can survey the edges of Seoul’s vast urban sprawl and the mountainous terrain beyond — only a handful of other skyscrapers in sight.
Lotte hired American elevator manufacturer the Otis Elevator Company to bring its double-deck Sky Shuttle to life.
Consisting of two attached cabins stacked on top of each other, it simultaneously carries passengers to separate floors. Other famous structures featuring this type of technology include the Canton Tower, in Guangzhou; the Petronas Towers, in Kuala Lumpur; the Eiffel Tower, in Paris; and the Burj Khalifa, in Dubai.
“A double-deck elevator was used because the observatory would be crowded at certain times of day,” Wonixuk Choi, manager of Lotte Corporation, tells CNN.
Inside the lift cabins, it feels like a video game — 15 OLED displays offer a virtual tour of Seoul during the 60-second ride.
Asia has made a name for itself in ground-breaking elevator technology in recent years.
In 2016, the Shanghai Tower opened, unveiling the fastest elevator in the world.
The Mitsubishi-designed lift runs at an incredible 20.5 meters per second (67 ft/s).
Standing at 2,074 feet (632 meters) tall, a fast lift was always going to be necessary for the world’s second tallest tower.
Also in China, Hitachi last summer unveiled the world’s second fastest elevator in Guangzhou’s tower CTF, which stands at 1,739 feet tall.
Its lift zooms from floors zero to 95 in an incredible 45 seconds — or 20 meters per second (65 ft/s).
Inside the elevator cabin, an indicator shows passengers how fast they are going, perhaps to prove that they aren’t being cheated.
