樂天世界塔

At 123 stories and 555 meters, Lotte World Tower is South Koreas tallest skyscraper and one of the tallest buildings in the world. The observation deck Seoul Sky offers breathtaking 360-degree views of the entire Seoul metropolitan area, with a glass floor section that is not for the faint-hearted. The tower complex includes Lotte World Mall, an aquarium, a concert hall, and the Lotte World amusement park next door. For tourists, the tower serves as Seouls ultimate viewpoint — on clear days you can see all the way to the West Sea. Time your visit for sunset to watch Seoul transform from day to night.
