Government Complex Sejong Rooftop Garden

Certified by Guinness World Records in 2016 as the longest continuous rooftop garden on Earth, the Government Complex Sejong Rooftop Garden is an architectural triumph of modern Korea. Spanning 3.6 kilometers in total length across a continuous serpentine ribbon of 15 interconnected ministry buildings, the garden encompasses 79,194 square meters of elevated greenery designed to symbolize the flight of a dragon undulating above the administrative capital.

The sky garden features over 1.17 million plants across 218 species, arranged in distinct thematic ecological zones including Herb Gardens, Medicinal Plant Plots, Native Korean Wildflower Walks, and Orchard Pavilions. The structural engineering incorporates specialized lightweight cellular soils, drip-irrigation water recovery systems, and panoramic cantilevered glass viewing platforms providing 360-degree vistas over the central administrative boulevard.

Spring brings blooming cherry trees, Korean forsythia, and royal azaleas bursting along the skyway railings. Summer showcases verdant flowering trumpet creepers and shade vines draping pergolas. Autumn is radiant with silver pampas grasses and fiery maple leaves set against sweeping views of the Geumgang River, while winter offers crisp, high-visibility panoramas of snow-draped government plazas.

Admission is completely free of charge. However, strict national security protocols require every visitor—both Korean citizens and foreign tourists—to present an original valid government-issued photo ID or passport. Online reservations can be secured through the Government Building Management Agency website or Naver Booking. Unreserved walk-in slots are subject to daily on-site security capacity limits.

The sky garden is designed with comprehensive barrier-free access. High-speed security elevators at Building 6 transport wheelchair users directly to the roof level. The 3.6-kilometer walkway is completely step-free with smooth composite decking, gentle ramp grades under 4%, and continuous stainless-steel safety handrails. Complimentary wheelchairs and motorized escort buggies are available for mobility-impaired visitors.

Surrounding the government complex in Eojin-dong, popular ministry dining hubs serve exceptional meals: try Prime Hanwoo Bulgogi hot pots, royal bibimbap in hot brass bowls, charcoal-grilled pork neck fillets, and refreshing buckwheat Pyongyang naengmyeon at commercial plazas along Bangchukcheon Stream.

Vegetarian diners can enjoy customized wild mountain vegetable set menus (sanchae jeongsik) and bubbling soybean paste stew (doenjang-jjigae) without meat at the government commercial concourses. High-end cafes on the ground level of Building 6 serve organic oat milk beverages, plant-based bakery treats, and fresh citrus smoothies.

Premier photo spots: the official Guinness World Records certification monument located at the 6th-floor rooftop landing, the curved dragon-spine walkway looking along the serpentine roofline toward Mount Jeonwol, and the glass observatory framing the distant blue dome of Sejong Lake Park.

As a Tier-1 National Security Facility, strict visitor regulations apply. Luggage, large backpacks, and any hazardous materials must be stored in security lockers at the ground floor check-in. Photographing government office interiors or sensitive communication antennae from the roof is strictly forbidden. Visitors must stay with their assigned tour group and security escort at all times.

Trained security marshals and certified tourist guides accompany all walking tours. Automated defibrillators (AEDs) and emergency panic call buttons are stationed at 100-meter intervals along the roof deck. For reservation support and interpretation, call the Complex Management Office at 044-200-1499 or the 1330 Korea Travel Hotline.

Visitors descending from the rooftop can seamlessly walk into Sejong Lake Park and the National Library of Korea, Sejong, both situated less than 800 meters east of the complex.

Q: Can foreign tourists join the tour without a Korean resident card? A: Yes. Foreign visitors simply need to bring their physical original passport for identity verification at the Building 6 check-in desk.
