Yeongjo Taesil Gabong Uigwe (Royal Protocol on Augmenting King Yeongjo’s Placenta Chamber)

This protocol contains a record of everything related to the ceremony involved in the 1729 augmentation of King Yeongjo’s placenta chamber in Museong-ri, Nangseong-myeon, Sangdang-gu, Cheongju-si. Yeongjo's placenta chamber should ordinarily have been reconstructed with stone immediately after his enthronement, but Yi In-jwa's Rebellion and repeated drought in the Cheongju region at that time delayed that. It was not until October of 1729 (fifth year of the reign of King Yeongjo) that the placenta chamber was reinforced with stone under the recommendation of the Ministry of Rites.
