Fortress Wall of Seoul, Seoul

The Fortress Wall of Seoul, or literally the Seoul City Wall is a series of walls made of stone, wood and other materials, built to protect the city of Seoul against invaders. The wall was first built in 1396 to defend and show the boundaries of the city, surrounding Hanyang in the Joseon Dynasty. At that time, it was called Hansung. The wall stretches 18.6 km along the ridge of Seoul's four inner mountains, Bugaksan, Inwangsan, Naksan and Namsan. At present, a 12-km section of the wall is designated as Historic Site No. 10 and is protected accordingly, along with the gates, water gates, and signal fire mounds. The northern, eastern, and southern sections of Mt.Nam walls have undergone extensive restoration work, having sustained damage or been entirely destroyed during Japanese imperial rule. ()
