The Grand Greenhouse standing north of Chundangji Ponds is a glasshouse designed by Hukuba Hayato, a Japanese who also designed the Japanese Imperial Arboretum, and built by a French company. The buildings made by the Japanese colonial authority were demolished during the process of restoring Changgyeonggung Palace except for the glasshouse. The building was spared for its architectural value, as it is the first building to appear in Korea whose structure is consisted of steel, timber and glass. The greenhouse was built along with the zoo according to the decision of the Japanese colonial authority to please King Sunjong (r. 1907-1910) who was staying in Changdeokgung Palace and used for the display of rare plants including ornamental plants from the tropical region. It began to be used for the cultivation of Korean native plants after the completion of the restoration of Changgyeonggung Palace in 1986, and was designated as the Registered Heritage No. 83 in 2004.
