Sujeongjeon was used by various government offices over time. During the reign of Sejong the Great, it was a key facility involved in the invention of the Korean script Hangul. The building was destroyed in 1592, during the Imjin War.^[3][2] One of its annex buildings had a fire in 1813.^{[4][clarification needed]}

It was reconstructed in 1867 and used as a side hall for Sajeongjeon.^[5] This form of the building has largely persisted to the present.^[6] From 1872 to 1875, it stored Gojong's ritual portrait.^[5] In 1894, it was used by the Reform Council [ko]. Its surrounding buildings were destroyed by 1915 for the Chōsen Industrial Exhibition.^[3] It then become the only remaining government office in the palace.^[7] It became used as a museum building for various artifacts from Central Asia.^[8] From October 4, 1966^[7] until 1975,^[6] it was occupied by a predecessor to the National Folk Museum of Korea.^[7]
