Source-derived summary

The 63 Building (Korean: 63빌딩; RR: Yuksam Building), officially called 63 SQUARE (formerly Hanwha 63 City), is a skyscraper on the island of Yeouido, overlooking the Han River in Seoul, South Korea. At 249.6 m (819 ft) high, it was the tallest building outside North America when it was opened on July 27, 1985, and it is the second-tallest gold-clad building in the world after Grand Lisboa in Macau. It stood as South Korea's tallest building until the Hyperion Tower surpassed it in 2003, but remained the country's tallest commercial building until the Northeast Asia Trade Tower was topped-out in 2009.

The 63 Building was built as a landmark for the 1988 Summer Olympics. 63 is something of a misnomer since only 60 floors are above ground level. Floors 61–63 are restricted areas. The skyscraper is the headquarters of Korea Life Insurance, Industrial Bank of Korea Securities, and other major financial companies.

The design of the structure is based on the Hanja character for person or human being (人 or in) in a subtle reference by the designers to the business of Daehan Life, the insurance company that constructed the building.

History

Construction

The 63 Building's construction broke ground in February 1980, at the height of South Korea's economic boom. It was built at a cost of 180 billion won, and construction was completed in May 1985.

The current lead gives the account dated anchors—1985, 2003, 2009, 1988—that can be checked directly. The linked authority record independently contributes the date 1985. Its value is orientation rather than verdict, with Building, skyscraper and South providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “63 Building”, the useful work is to connect “skyscraper in South Korea” to the records capable of establishing context and consequence.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 20, 2026. The linked authority identifier is Q22968. Authority coordinates are 37.520, 126.940. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
