63 Building is a skyscraper on Yeouido (island) in Yeongdeungpo-gu, Seoul in South Korea. Despite its name, it actually has 66 floors – 63 floors above ground and 3 floors underground. Construction started in February 1980, and was completed in May 1985. At that time, the name of the building was “Daehanlife 63 Building”, but the name of this has changed to “63 City.” It was the highest building in Asia at the moment of being built. It is now the 5th highest building in even Korea – the highest building in Korea is Northeast Asia Trade Tower in Incheon. But from now on, 63 Building is known as the most famous landmark in Korea.
