The first record of Gwangju Castle appears in the geography of Sejong Shilok, where it says 'Castle is built, it has a circumference of 972 steps', but no specific information (such as when the building was built) was given. However, because the fortress was built in Naju and Boseong in preparation for the invasion of the Joseon dynasty, the city of Gwangju is presumed to have been built in the early 15th century.
