Naksan was also called Naktasan, or Camel Mountain, as it's peak is shaped like the humped back of a camel, Naksan is located in the eastern part of Seoul, stretching to Jongno-gu, Dongdaemun-gu and Seongbuk-gu compared with Inwangsan to the west.

One of the four inner mountains in Seoul -- along with Namsan, Inwangsan and Bukaksan -- Naksan oduples the seat of the Blue Dragon in traditional theory of geomancy.

Based on the theory of geomancy in topography, Yi song-Gye or King Taejo, the founder of the Joseon Dynasty, chose Naksan as a symbolic representation of the blue dragon for protection and prosperity of the area, when selecting this city as it's capital. But it's mountain range was not long enough and it's spiritual energy was not solidly endowed compared with Inwangsan. Thus it is said that the title of Dongdeamun (the Great East Gate), Heunginmun, was renamed to include one more character into Heunginmun, in bid to address the lacking energy.

In planning towns and communities, our ancestors took into consideration even geographical fratures of surrounding mountains and wisely employed intangible measured to complement any ahortcomings, Naksan is mostly composed of granite, and there used to be dense forests, clean suseok (natural stones for appreciation) along the streams, as well as mineral stings.

Inpyeong Royal Prince, younger brother of King Hyojong of the Joseon Dynasty, had the Seokyang (sun set) Pavilion here as his residence. Also, there used to be Ihwa (pear flower) Pavilion and Ilwong (an old man) Pavilion established by a literary man named Lee Shim-won during King Youngjo's reign. Both pavilions were frequented by royal family members, literary man and artists.

After King Danjong of t Joseon dynasty was exiled to a remove site at Yeongweol in Gangwon-do, having been dethroned by his uncle, Suyang, his consort, Queen Jungsoon, used to climb up this mountain everyday and spent the rest of her whole life just looking towards the east in the direction of Yeongweol where her husband was in exile.

The Ssanggye-dong (double streams) valley at Naksan was onge known as one of the top five scene (scen) spots in Seoul, along with Samcheong, Inwang, Baekun and Cheonghak, because of it's extraordinarily shaped rocks and cliffs, dense forests and superb view of streams.

Before Japanese colonization, Seoul residents lobed to stroll in Naksan, well known for it7s clear streams and dense forests. There used to be residential village of the Yl family in Dongchon and also the residence of Ryu Gwan, otherwise know in his penname of Hajeong, a scholar of early Joseon era renowned for his loyalty and scholarly wisdom. His grandson, Yi Su-gwang with penname Jlbong, wrote his work, Jibongyuseol, at the Biudang which had been named in honor of his grandfather. It is one of numerous historical sites at Naksan.

この城郭は楕円形に近い。この城郭は、日本の侵略開始とともに、都市計画の名目のもと、一部が崩され、朝鮮戦争の時にさらに破壊されたが、ソウル市は1975年から総合的な城郭復元事業を始めた。
