Sujiksa, located east of the main gate, is the building where stewards, guards, and maintenance men were housed. Inside the structure are artifacts such as clothing, furniture, and other daily items. There artifacts were used by security, stewards, guards, and maintenance while at the palace.
The royal residence at a time was much bigger and required a larger amount of guards and soldiers for the protection of Heungseon Daewongun. He needed more protection as he grew powerful after his son, Yi Myeong-bok, better known as Emperor Gojong, ascended to the throne in 1863.
