About 63 Square

63 Square, long known as the 63 Building, is a gold-clad skyscraper on Yeouido island overlooking the Han River. At 249.6 m it was the tallest building outside North America when it opened on 27 July 1985, and it was built as a landmark for the 1988 Summer Olympics. It remains the world's second-tallest gold-clad building after the Grand Lisboa in Macau. Despite the name, only 60 floors are above ground; floors 61 to 63 are restricted areas.

What's inside

The 60th floor holds what is described as the world's highest art gallery together with an observation deck, from which visitors can see as far as Incheon on clear days. Glass-walled observation elevators show the city on the way up and down. The 59th floor has international restaurants. The lower floors house an indoor shopping mall of about 90 stores and an IMAX theatre; the building formerly also held a large aquarium. A convention centre and a banquet hall are inside as well.
