Namsan
Namsan is a 860 ft peak in the Jung-gu district of south-central Seoul, Korea. Known as Mount Mongmyeok in the past, it is now commonly referred to as Namsan (lit. "South Mountain"). It offers hiking, recreation, and views of downtown Seoul's skyline. The N Seoul Tower is located on top of Namsan. It is also the location of a smoke signal station called Mongmyeoksan Bongsudae, which was part of an emergency communication system until 1985.
