Deoksugung Palace, Historic Site No. 124, was not originally a royal palace. It was originally the residence of King Seongjong’s brother Wolsan Daegun (1454~1488). Since the palace was almost completely destroyed during the Imjin Japanese Rebellion in 1592, it was demolished from 1593 The then Deoksugung Palace was used as a palace. After Gojong abdicated to Sunjong in 1907, even though the royal palace had been moved back to Changdeokgung, Gojong still used this place as his residence. In order to pray for the long life of Emperor Gojong, Gyeongun Palace was called Deoksugung Palace. There were many buildings in Deoksugung Palace in the past, but now only Daehanmun, Junghwajeon, Gwangmyeongmun, Hyeomidang, Junmyeongdang, Geyundang, Hamnyeongjeon, Deokhongjeon and Seokjojeon remain within the 18,635-pyong area.
