Lotte World Tower and the vertical city above Seoul
Published on 08/20/2026 at 19:56 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Lotte World Tower is a supertall skyscraper in Seoul that pushes the idea of a mixed-use high-rise into a vertical city, with offices, homes, retail and an observatory stacked into a single tapering form completed in 2017.
A tapered supertall on the Han River
The tower stands in the Songpa District on the southern side of the Han River, forming a focal point on the skyline east of central Seoul.300 Olympic-ro in Songpa-gu places it within a dense cluster of commercial and entertainment sites rather than in an isolated business park. From ground to architectural tip it reaches a height around 555 m (1,821 ft), making it the tallest building in South Korea and one of the tallest skyscrapers worldwide.555 m architectural height
The profile narrows gradually as it rises, giving the facades a slender, elongated character that is distinct from the simpler rectangular towers elsewhere in the city.architectural height and completion The tower has over one hundred above-ground storeys, with structural descriptions referencing 123 levels above grade and a small lantern-like pinnacle above them.123 floors above ground At night the tapering mass reads as a single vertical stroke, while in daylight the pale cladding and vertical emphasis set it apart from darker, lower neighbours beside the river.
Architecture, structure and programme
Lotte World Tower was designed by Kohn Pedersen Fox Associates, a New York-based practice known for high-rise projects in dense urban settings.architect Kohn Pedersen Fox Associates Structural engineering was handled by Leslie E. Robertson Associates, a firm with extensive experience in tall-building engineering.Leslie E. Robertson Associates Construction progressed over much of the 2010s, with the project completed and opened to the public in 2017.completion in 2017 Architectural descriptions highlight a mixed programme including retail at the base, office space, a hotel and residential units higher up, topped by public observatory levels.
Structurally, the building uses a reinforced concrete core surrounded by concrete mega-columns connected through steel outrigger and belt truss systems at selected levels.concrete core and mega-columns The lateral-load-resisting system therefore combines the stiffness of the core with the strength of these outer columns and the linking trusses, a common strategy for supertall buildings. The uppermost lantern-like section is described as a steel diagrid frame behind a translucent curtain wall, giving the very top a slightly different texture when seen from a distance.steel diagrid lantern Internally, long-span spandrels support office floors between the mega-columns, while mechanical floors and refuge levels sit at intervals to serve the stacked uses.
Seoul Sky and the world above the city
High near the top of the tower sits Seoul Sky, the complex of observation spaces that turns the upper levels into a visiting destination in its own right.Seoul Sky observatory Descriptions place the main observatory floors from level 117 to level 123, with the principal enclosed deck on floor 118 at an elevation close to 500 m (1,640 ft) above ground.observation deck near 500 m The approach begins with high-speed lifts sometimes described as “Sky Shuttle” elevators, taking visitors from lower levels directly to the upper sky lobby.
Once on the upper floors, visitors encounter multiple levels of viewing spaces rather than a single platform. Facilities include indoor areas with broad glazing over Seoul and the Han River, a glass-floored section recorded in Guinness World Records as the highest glass floor observatory in Korea, and terraces that bring the experience closer to the outer skin of the building.highest glass floor observatory The height means that a clear day offers views across large parts of metropolitan Seoul, the river corridors and distant hills, framed by the tower’s tapering structure itself.
Visiting Lotte World Tower: what travellers from Western Europe should know
- Lotte World Tower stands in Songpa-gu on the south side of the Han River in Seoul, with access from major city roads and nearby public transport interchanges serving the surrounding entertainment district.
- The interior includes high-rise lifts and long escalators, while the ascent to the Seoul Sky levels involves fast elevators and movement through several storeys of indoor space.
- The tower sits within an urban environment of paved plazas and indoor malls, so ordinary city footwear is adequate; the main effort lies in the vertical travel inside the building rather than in outdoor terrain.
- South Korea’s official language is Korean and the currency is the won.
- Entry requirements depend on your nationality; UK travellers can check the FCDO travel advice at gov.uk/foreign-travel-advice, Irish travellers the Department of Foreign Affairs at ireland.ie.
