Government Complex Sejong Rooftop Garden

Character

Fifteen government buildings share one continuous planted roof. The garden runs for about 3.6 kilometres across Government Complex Sejong, crossing between ministry blocks that appear separate at street level

That continuity came from the master plan for the administrative city. The government district was conceived as a low, horizontal alternative to a conventional cluster of towers, with bridges and roof gardens connecting institutions across the complex. The roof turns that planning idea into a piece of landscape large enough to walk through

Planting softens the scale without hiding the infrastructure. Herb and medicinal gardens, fruit and berry areas, vine tunnels and seasonal planting sit above offices and meeting rooms. From higher sections, the view opens toward Sejong Lake Park and the Presidential Archives

The experience

The unusual part is the sustained elevation. A guided visit stays above ground level long enough for the roof to stop feeling like an amenity attached to a building and start feeling like a linear park laid across an administrative district

The route also changes how the complex reads. Bridges that are easy to miss from the street become the joints between buildings. Ministry blocks, courtyards, roads and nearby civic landmarks appear from an angle normally reserved for employees

The garden itself stays low-key and varied. Planting shifts between small themed sections, open paths and lookout points; the scale comes from the distance covered and the fact that the path keeps continuing across another government roof

History

Government Complex Sejong began receiving central government agencies in 2012 as the new administrative city took shape. Its master plan emphasized a “flat city,” using low buildings, bridges and shared roof space to connect ministries horizontally

The rooftop landscape also borrowed from sunseongnori, the traditional practice of walking around a fortress wall and looking both inward and outward. Here the wall became an elevated path across the government complex, with views into the ministries and out toward the developing city

Guinness World Records measured 79,194 square metres of rooftop garden in January 2016 and recognized Government Complex Sejong as the record holder for the largest rooftop garden. The official complex now describes the connected roof as roughly 3.6 kilometres long across 15 buildings

Before you go

Public access runs through escorted tours. The operating season avoids the hottest and coldest parts of the year, and tours can be cancelled in severe weather

Advance booking and on-site registration are both used, and photo identification is required. The route is one-way, so the finish may be some distance from the starting point; public transport is often simpler than returning to a parked car at the starting building
