Gongsanseong was initially known as Ungjinseong and subsequently as Gongsanseong during the reign of the Goryeo Dynasty. It occupies an area of {{Convert|20|ha}}, presently in the Geumseong-dong and Sanseong-dong districts. It was unearthed during the archaeological excavations done after 1980s, when the constriction methods in building the forts's rampart, the royal palace, and the associated structures of the royal palace were revealed. The fort is located atop the Gongsan mountain (elevation {{Convert|110|m}}) and extends over a length of {{Convert|2666|m}}, with its stone wall in {{Convert|1925|m}} length and the balance {{Convert|735|m}} made of earth.
