Lock

This lock is shaped into the Hangul character “ㄷ” with the inscription, “東宮衙鎰”. The word 東宮 refers to the palace of the Crown Prince, which confirms that Wolji was the location of Donggung Palace. It was discovered in addition to other locks, each with inscriptions in Chinese characters, “思正堂北宜門” and “合零闡鎰”. The former indicates that the palace had annexed buildings called Sajeongdang House (思正堂) and Buguimun Gate (北宜門).
