Northern Semi-circular Wall

This semi-circular wall on the outside of Janganmun Gate was built to strengthen the gate’s defenses. In traditional Korean fortresses, the entrance of this type of ancillary wall was usually built on the side where the wall meets the large gate. However, this semi-circular wall has its entrance constructed at the center to better facilitate the transportation of people and goods. There are five holes above the entrance of this wall which were designed to release water in case of a fire. In Korea, only Hwaseong Fortress has this unique feature.During the Korean War (1950-1953), the wall and the roof above the entrance were severely damaged and were rebuilt to their current appearance in 1975.
