In the Joseon royal family, there was a department called “Naemyeongbu”, which ranked the royal ladies. It controlled the hierarchy of women who served in the royal court. In the absence of a queen consort, the king's mother and her grandmother took charge of the administration. Yanghwadang Hall was the place used to meet official visitors. It was located on the east side of Tongmyeongjeon Hall, and its name means “to grow harmony”.

The purpose of Yanghwadang Hall has significantly changed three times. When it was first built in 1484, it served as a reception hall for the king to meet Confucian scholars. However, it was burned down during the Japanese invasion of Korea. After the reconstruction in 1633, it was used as a place for lamentation ceremonies, which were a rite of mourning in the direction of the mortuary without directly visiting on the day of a state funeral or the memorial day for the death of a king or queen. It then became a place for meeting the Qing envoys after the Qing invasion of Joseon. King Injo stayed and met the Qing envoys to conduct government affairs at Yanghwadang Hall after surrendering to the Qing. The current building was rebuilt in 1834.

The architectural style of Yanghwadang Hall is distinct. Parapets were added to the front and back of the structure. The hall was used as a residence for women, so its parapets were likely either used for decoration or modeled after the Qing Dynasty's architectural style.
