Injeongmun is the main gate of Injeongjeon at Changdeokgung in Jongno. It is the last gate passed through when entering Injeongjeon after Jinseonmun. The gate was destroyed during the Imjin War and rebuilt under Gwanghaegun, and it was rebuilt again after burning down under Yeongjo. It was converted into an exhibition hall during the Japanese occupation and restored to its original form in the 1990s.
