Opening of the Fortress wall in Mt. Bugaksan, Seoul
- April 5, 2007


Located at the rear of the Blue House, the presidential residence, Bugaksan Mountain had been closed off as a military reservation for the purpose of national security ever since North Korean commandos slipped over the mountain to attack the presidential mansion on January 21, 1968. Sukjeongmun Gate (the North Gate of Seoul), one of the four main gates of Seoul together with the South, East and West gates located within this Bugaksan Mountain, was also closed off.
