So far, two roof tile pieces, with the line saying 'The Seal of Namgung' imprinted upon it, have been found both from the National Gyeongju Museum site and from the ruins at the address of 696-2, Dongcheon-dong, Gyeongju. There have been many suggestions concerning the true nature of this 'Namgung.' Some people thought of it as a part of a palatial structure, while others considered it to be a governmental office for handcraft manufacturing industry.
However, close analysis of the relics and the vestiges shows us that both sites had something to do with ancestral rituals and ceremonies. In addition, both pieces of roof tiles seem to have been made between the mid-9th century and the 10th, considering the level of technical manufacturing featured by them. It is also determined that the term 'Namgung' was once used as another name of the Ye-bu office[Ministry of Protocols], based upon the contents written upon the stele of Monk Nang'hye of the Seongju-sa temple, which was built at the same period as these tiles.
So, it seems that 'Namgung' was a term that referred to the Shilla dynasty's Ministry of Protocols. And because the term only appeared in a specific time period(from the mid-9th century through the early 10th), it is surmised that the term finally emerged when ancient official titles were being replaced in the middle of the 9th century.
