Seoul’s new Lotte World Tower is a marvel of engineering, adding 123 floors of class to the banks of the Han River in South Korea’s capital.
Among its spectacular features, reports Lonely Planet, are the world’s highest swimming pool and observation deck, as well as an immense concert hall and even an aquarium.
For tourists interested in visiting the world’s fifth-tallest building, there’s also a seven-star luxury hotel and the Lotte World Mall, which, when combined, the building’s developer expects to attract more than 50-million tourists.
The building also features apartments and parking for permanent residents, as well as office levels for companies looking to invest in some seriously premium property.
Last year, two urban explorers illegally climbed the then-unfinished tower, before scaling a crane perched atop it. They’ve since been banned from the building, but their immensely popular video can be watched below.
