Located on a major transportation route, this place, which has been called Joryeong since the early Goryeo Dynasty, was a barrier of great military importance between Seoul and Gyeongsang-do. It had high strategic importance since the troops of two Japanese generals, Konishi Yukinaga and Kato Kiyomasi, converged here during the Japanese Invasion of Korea in 1592. The court counted on General Sin Rip to defend Joryeong, but he was forced to retreat to Chungju. He was defeated by the Japanese military in Tangeumdae Heights, Chungju. Recognizing its military importance, the court steadily discussed the building of a gate there, and King Sukjong (1674-1720) had three gates connecting Mungyeong and Chungju fortified in 1708. The first was named Juheulgwan, the second, Jodongmun or Jogokgwan, and the third, Joryeonggwan. Jodongmun became the more important barrier gate since Sin Chung-won built a fort here in the 25th year of the reign of King Seonjo after the Japanese Invasion of Korea in 1592. In the 34th year of the reign of King Sukjong when Joryeongsanseong Fortress was built, the original fort built by Sin Chung-won to the north of Maebawi Rock was restored to serve as the outer wall, and the gate was then renamed Jogokgwan. Now, It was restored.
