There is on a hilly area behind Tongmyeongjeon Hall a site where King Jeongjo built a residence called Jagyeongjeon Hall for his mother Royal Lady Hyegyeonggung Hong. The king chose the site because it had a fine vantage point overlooking Gyeongmogung Shrine which housed the spirit table of his father, Crown Prince Sado, who died a tragic death before being crowned. When it stood, Jagyeongjeon displayed a grander structure than even Tongmyeongjeon, traditionally used as the official residence for queen consorts, highlighting the King Jeongjo's filial piety for his mother. The building was destroyed by fire in 1873, leaving the site to a royal depository library which was built in 1911 by the Japanese colonial authority. The Japanese style building was demolished in the 1980s when the Korean government launched the Changgyeonggung Palace Restoration Plan.
