Yongammun is one of the designated sub-gates of Bukhansanseong Fortress, which was largely expanded and rebuilt in 1711 to defend Seoul during times of invasion.
The gate takes its name, which translates to Dragon Rock Gate, from the surrounding rock formations resembling a dragon.
Unlike the main fortification gates, sub-gates like Yongammun were intentionally built in hidden or narrow ravines to facilitate secret military communication.
The fortress walls connected to the gate utilize the natural granite cliffs of Bukhansan as part of their defensive barrier.
Yongammun is a traditional stone gate located along the historic Bukhansanseong Fortress wall in the northern mountains of Seoul. Situated at an elevation near the mountain ridges, it served as one of the key hidden gates or sub-gates used to control troop movements and supply lines during the Joseon Dynasty. The gate features a classic arched stone entrance topped by a traditional Korean parapet structure. It sits directly on popular hiking routes connecting major peaks within Bukhansan National Park. The site offers hikers a tangible look at Korea's defensive architecture constructed in steep, rugged terrain.
