Seun Rooftop is an observation deck on the ninth floor of the exterior of Sewoon Sangga, looking down over central Seoul. From it, Jongmyo, Bukhansan, Bugaksan, Namsan and the surrounding high-rises are visible in one view, showing old buildings and the modern city together. An elevator in Sewoon Sangga goes up to benches and full-glass railings. The ninth-floor observation deck is currently closed.
