Injeongjeon Hall, a South Korean National Treasure, is the throne hall of Changdeokgung Palace, it was used for major state affairs including the coronation of a new king and receiving foreign envoys. Originally built in 1405, it was rebuilt in 1610 after being burned down during the 1592 Japanese invasion, and a third time in 1804 after being destroyed by a fire.
Changdeokgung Palace, “Prospering Virtue Palace” — is set within a large park in Seoul. It is one of the “Five Grand Palaces” built by the kings of the Joseon Dynasty (1392–1897). The buildings of Changdeokgung blend with the natural topography of the site instead of imposing themselves upon it. It, like the other Five Grand Palaces in Seoul, was heavily damaged during the Japanese occupation of Korea (1910-1945). Currently, only about 30% of the original structures survive at Changdeokgung.
