Located at the top of South Korea's tallest building, the Seoul Sky Observatory offers 360-degree views of the capital. It stands at 555 metres above the ground, and occupies the top seven floors of the 123-storey Lotte World Tower. You will ride the Sky Shuttle, a high-speed elevator that brings you to the observation deck in less than a minute. Aside from a café and souvenir shop, Seoul Sky also features an art exhibition reflecting the history and culture of Korea.
