Gyeonghoeru, Gyeongbokgung palace (경희루, 경복궁)
  Gyeonghoeru (Hangul: 경회루; Hanja: 慶會樓), also known as Gyeonghoeru Pavilion, is a hall used to hold important and special state banquets during the Joseon Dynasty. It is registered as Korea's National Treasure No. 224 on January 8, 1985.
  The first Gyeonghoeru was constructed in 1412, the 12th year of the reign of King Taejong, but was burned down during the Japanese invasions of Korea in 1592. The present building was constructed in 1867 (the 4th year of the reign of King Gojong) on an island of an artificial, rectangular lake that is 128 m wide and 113 m across.
