The statue of King Sejong was dedicated on 9 October 2009, in a ceremony attended by attended by President Lee Myung-bak and other Korean government official, on a Hangul Day in celebration of the 563rd anniversary of the invention of the Korean alphabet by King Sejong, two months after the Gwanghwamun Plaza opening. The golden statue is 6.2 meters high (another source gives the statue height as 9.5 meters and yet another, 6.7 meters) and weights 20 tons. The king has one hand raised and another placed on a book. Sides of the statue display all of the hangul alphabet characters. In front of the statue there are small models of a celestial globe, a rain gauge, and a sundial, the invention of which is also traditionally attributed to King Sejong in Korea.

Hangul
The "Hunmin Jeong-eum" states that King Sejong adapted the ("gojeon", ""Gǔ" Seal Script") in creating the Korean alphabet. The has never been identified. The primary meaning of "gǔ" is "old" ("Old Seal Script"), frustrating philologists because the Korean alphabet bears no functional similarity to Chinese "zhuànzì" seal scripts. However, Ledyard believes "gǔ" may be a pun on "Měnggǔ" "Mongol", and that is an abbreviation of "Mongol Seal Script", that is, the formal variant of the 'Phags-pa alphabet written to look like the Chinese seal script. There were 'Phags-pa manuscripts in the Korean palace library, including some in the seal-script form, and several of Sejong's ministers knew the script well.
