Gangnyeongjeon (강녕전), also called Gangnyeongjeon Hall, is a building used as the king's main sleeping and living quarters. The building contains the king's bed chamber and was first constructed in 1395, the fourth year of King Taejo. Destroyed during the Japanese invasions of Korea in 1592, the building was rebuilt when Gyeongbokgung was reconstructed in 1867, but it was again burned down by a major fire on November, 1876 and had to be restored in 1888 by the orders of King Gojong.
However, when Huijeongdang of Changdeokgung Palace was burned down by a fire in 1917, the Japanese government dismembered the building and used its construction materials to restore Huijeongdang in 1920. The current building was rebuilt in 1994, meticulously restoring Gangnyeongjeon to its original specifications and design.
Gangnyeongjeon consists of fourteen rectangular chambers, each seven chambers located to the left and right side of the building in a layout out like a checkerboard, and corridors. The king used the center chamber while the court attendants occupied the other side chambers to protect, assist, and to receive orders. The building rests on top of a tall stone foundation, and a stone deck or veranda locates in front of the building.
