The day is also marked with various activities like public speeches, Taekwondo and other performances by various artists. All schools, public offices and private offices remain closed to honour the South Korean Foundation Day. A special event was to be held in downtown Seoul at the Sejong Center for the Performing Arts with some 3,000 people in attendance as well as Prime Minister Kim Hwang-sik.On this day, a simple ceremony is usually held at an altar on top of Mt. Manisan in Ganghwado Province. The altar is said to have been erected by Dangun to offer thanks to his father and grandfather in heaven.After an armistice was signed with North Korea in 1953, South Korea achieved rapid economic growth with per capita income rising to roughly 17 times the level of North Korea.
