At 555 metres and 123 floors, the tallest building in Korea. The Seoul Sky observatory sits on floors 117 to 123, and the lift takes about a minute. On the 118th floor a glass-floor area shows the ground straight below. On a clear day you see the Han River, the whole city and mountains far away. Lotte World Mall and Seokchon Lake are right below, so it fits into one outing.
