Seoul’s tallest building and the view that puts the whole city in perspective

555 metres, 123 floors, the tallest building in Korea. The observatory at the top (Seoul Sky) gives you the best panoramic view of the city. Connected to Lotte World Mall and the theme park in Jamsil.

Yes, if you want the single best panoramic view of Seoul. At 555 metres and 123 floors, this is the tallest building in Korea and you can see the Han River, mountains, and the full sprawl of the city from the top. The observatory (Seoul Sky) sits on floors 117-123 and the elevator gets you there in about a minute.

Skip it if heights genuinely bother you, or if the weather is hazy. The view loses most of its impact on low-visibility days.

Floor-to-ceiling glass walls on every side. On a clear day you can see surprisingly far. Mountains, the river bending through the city, and the grid of neighborhoods clicking into place below you. It is one of those views that helps you mentally map Seoul.

A Guinness-certified glass floor observation deck. You stand on transparent panels and look straight down 118 floors. Some people freeze, some people love it. Either way, it is a memorable few minutes.

An outdoor terrace near the top. Fresh air and an unobstructed view without glass in the way. Wind can be strong up here.

A guided outdoor walk on a bridge at 541 metres. You wear a safety harness and walk across the outside of the building. It is weather-dependent, limited capacity, and has age/height/weight restrictions. Book well in advance if this interests you.
