The side of Huijeongdang, in Changdeokgung palace, Seoul, South Korea. Huijeongdang was originally built as the king's bed chamber, but was later changed to be used as the main office for the king when the king's study, Seonjeongjeong was found to be too small. The building was burnt down in 1917 and then rebuilt, but the style of the new building is quite different to the original.
Changdeokgung palace was built as a secondary palace to Gyeongbokgung by King Taejong in 1405. He felt that the location of Gyeongbokgung wasn't auspicious enough according to the principles of geomancy. Taejong ascended to the throne after assassinating his half-brothers and the powerful official Jeong Do-jeon at Gyeongbokgung, so this probably also contributed to his reasons for wanting a new palace.
