"Constructed in 1396, Seoul’s great fortress walls snake around the 11.5-mile perimeter of the old city, straddling the ridges between Bugaksan, Naksan, Namsan, and Inwangsan mountains. Punctuated by ancient gates, the walls now function as hiking paths. From Dongdaemun Gate you can go to scenic observation points in Naksan Park and hillside Ihwa Mural Village, or walk up Bugaksan, which backs into the quiet, wooded—and heavily protected—presidential compound. The rampart in Namsan is another popular route, leading from the base of the mountain to its crowning N Seoul Tower."
