Serving as the main gate of Injeongjeon Hall, Injeongmun Gate was established in 1405 (5th year of King Taejo’s reign during the Joseon dynasty). Later on, the gate was destroyed by multiple fires during the Imjin War (Japanese invasion of Korea in 1592), therefore current form of the establishment displays designs that are more often seen in the late 19th century's. In addition, a lot of subsidary marks and buildings are removed from the original places and relocated passing the time, however, still remains to represent prestigious ambience.

Injeongmun Gate served as the place for several coronation ceremonies of kings, prince's succession of throne, and many other national affairs celebrated by the royal members who gathered and aligned around this gate.
