Seoul

{{main|Names of Seoul}}

Traditionally, seoul ({{Korean|hangul=서울|labels=no}}) has been a native Korean (as opposed to Sino-Korean) common noun simply meaning 'capital city.' The word seoul is believed to have descended from Seorabeol (서라벌; historically transliterated into the Hanja form {{Lang|ko|徐羅伐}}), which originally referred to Gyeongju, the capital of Silla.{{Cite web |author=정 |first=구복 |title= |script-title=ko:서울 |url=https://encykorea.aks.ac.kr/Article/E0027956 |access-date=August 17, 2024 |website=Encyclopedia of Korean Culture}}{{Cite journal |last=Ju |first=Bo Don |date=2019 |title=Gyeongju, a City of History |url=http://www.ijkaa.org:443/v.13/0/15/8 |journal=Journal of Korean Art & Archaeology |language=en |volume=13 |pages=15–23 |doi=10.23158/jkaa.2019.v13_02 |issn=2951-4983}}

Wiryeseong ({{Korean|labels=no|위례성|慰禮城}}), the capital settlement of Baekje, was located within the boundaries of modern-day Seoul. Seoul was also known by other various historical names, such as Bukhansan-gun (북한산군; 北漢山郡, during the Goguryeo era), Namcheon ({{Korean|labels=no|남천|南川}},{{Cite web |title=Monument on Bukhansan Mountain Commemorating the Border Inspection by King Jinheung of Silla |url=https://db.history.go.kr/item/compareVerticalViewer.do?levelId=gskh_003_0010_0090_0020&oneLevelId=gskh_003_0010_0090_0020&otherLevelId=gskh_003_0010_0090_0030 |url-status=live |archive-url=https://web.archive.org/web/20230122050003/https://db.history.go.kr/item/compareVerticalViewer.do?levelId=gskh_003_0010_0090_0020&oneLevelId=gskh_003_0010_0090_0020&otherLevelId=gskh_003_0010_0090_0030 |archive-date=22 January 2023 |access-date=22 January 2023 |website=National Institute of Korean History}} during the Silla era), Hanyang ({{Korean|labels=no|한양|漢陽}}, during the Northern and Southern States period), Namgyeong (남경; 南京, during the Goryeo era), and Hanseong ({{Korean|hangul=한성|hanja=漢城|labels=no}}, during the Joseon era). The word seoul was used colloquially to refer to the capital as early as the 17th century.Hendrick Hamel, a 17th-century Dutch sailor who was shipwrecked on Jeju Island, referred to the Joseon capital as Sior in his book "Hamel's Journal and a Description of the Kingdom of Korea, 1653–1666." Refer to the English translation of the book on this [https://www.hendrick-hamel.henny-savenije.pe.kr/holland6.htm website] created by Dr. Henny Savenije, a Dutch scholar known for his research on Hamel.

Under subsequent Japanese colonization, Hanseong was renamed as Keijō (京城, literally 'capital city'){{efn|Also referred to as Gyeongseong ({{Korean|labels=no|경성|京城}}) via its Korean pronunciation.}} by the Imperial authorities to prevent confusion with the Hanja '{{lang|zh-hant|{{linktext|漢}}}}' (a transliteration of a native Korean word {{Korean|hangul=한|rr=han|labels=no|lit=great}}), which may also refer to the Han people or the Han dynasty in Chinese and is associated with 'China' in Japanese context.{{Cite book|url=https://books.google.com/books?id=pDZYDwAAQBAJ&q=Hanseong+was+renamed+to+Keij%C5%8D&pg=PT136|title=Eclipsed Cinema: The Film Culture of Colonial Korea|date=22 March 2017|isbn=9781474421829|last1=Kim|first1=Dong Hoon|access-date=21 November 2020|archive-date=14 July 2022|archive-url=https://web.archive.org/web/20220714164921/https://books.google.com/books?id=pDZYDwAAQBAJ&q=Hanseong+was+renamed+to+Keij%C5%8D&pg=PT136|url-status=live}} After World War II and the liberation of Korea, Seoul became the official name for the Korean capital.

Unlike most place names in Korea, as it is not a Sino-Korean word, 'Seoul' has no inherently corresponding Hanja (Chinese characters used in the Korean language). Instead of phonetically transcribing 'Seoul' to Chinese, in the Chinese-speaking world, Seoul was called Hànchéng ({{lang-zh|s= 汉城|t=漢城|labels=no}}), which is the Chinese pronunciation of Hanseong. On 18 January 2005, the Seoul Metropolitan Government changed Seoul's official Chinese name from the historic Hànchéng to Shǒu'ěr ({{lang-zh|links=no|s=首尔|t=首爾|p=|labels=no}}). Shǒu'ěr is a phono-semantic match incorporating both sound and meaning (through 首 meaning 'head', 'chief', 'first').{{cite web |url=http://news.naver.com/main/read.nhn?mode=LSD&mid=sec&sid1=104&oid=022&aid=0000126138 |script-title=ko:서울특별시표기 首爾로...중국, 곧 정식 사용키로 |language=ko |publisher=Naver News |date=23 October 2005 |access-date=10 February 2012 |archive-date=25 January 2016 |archive-url=https://web.archive.org/web/20160125042516/http://news.naver.com/main/read.nhn?mode=LSD&mid=sec&sid1=104&oid=022&aid=0000126138 |url-status=live }}{{Cite web |title=Chinese Naming Crisis Danger Opportunity Summer 2006 – Good Characters |url=http://goodcharacters.com/newsletters/summer2006-seoul-korea.html |url-status=live |archive-url=https://web.archive.org/web/20180930195048/http://goodcharacters.com/newsletters/summer2006-seoul-korea.html |archive-date=30 September 2018 |access-date=18 November 2018 |website=goodcharacters.com}}

Around the collapse of Wiman Joseon (194–108 B.C.) in the northern part of Korea, numerous refugees went south to the Han River basin, which was then controlled by Jin (4th–2nd century B.C.). These diverse peoples brought with them culture and technology of the Chinese Warring States that accelerated the region's progress into the Iron Age. Their arrival destabilized the region; Jin disintegrated, and dozens of statelets emerged that competed for influence in the Han River basin.{{Sfn|Seoul: A 2,000-Year History Vol. 3|2015|p=|pp=49–52, 114}}

Baekje (18 B.C. – 660 A.D.), once one of the statelets in the Mahan confederacy, became the dominant local power by the 2nd century A.D.{{Sfn|Seoul: A 2,000-Year History Vol. 3|2015|p=|pp=52–53, 66, 68–69}} Its capital was in Wiryeseong; Wiryeseong's specific location is not known with certainty, but it is believed to have been within the bounds of the ramparts Pungnaptoseong and Mongchontoseong.{{Sfn|Seoul: A 2,000-Year History Vol. 3|2015|p=114|pp=}} This area is now in southeastern Seoul.{{Sfn|Seoul: A 2,000-Year History Vol. 3|2015|p=136|pp=}}{{Cite web |title=Pungnap-dong Toseong Fortress (서울 풍납동 토성) |url=https://english.visitkorea.or.kr/svc/whereToGo/locIntrdn/rgnContentsView.do?vcontsId=80882&menuSn=351 |access-date=2024-12-02 |website=VisitKorea.or.kr |publisher=Korea Tourism Organization |language=en}}

In July or August 553, Silla took the control of the region from Baekje, and the city became a part of newly established Sin Province ({{Korean|hangul=신주|hanja=新州|labels=no}}).{{Cite web |title=Samguk Sagi Silla Jinheung 19 |url=https://db.history.go.kr/item/oldBookViewer.do?levelId=sg_004_0040_0190 |url-status=live |archive-url=https://web.archive.org/web/20230122045955/https://db.history.go.kr/item/oldBookViewer.do?levelId=sg_004_0040_0190 |archive-date=22 January 2023 |access-date=22 January 2023 |website=National Institute of Korean History}}{{Cite web |title=Samguk Sagi Baekje Seong 19 |url=https://db.history.go.kr/item/oldBookViewer.do?levelId=sg_026_0060_0190 |url-status=live |archive-url=https://web.archive.org/web/20230122045942/https://db.history.go.kr/item/oldBookViewer.do?levelId=sg_026_0060_0190 |archive-date=22 January 2023 |access-date=22 January 2023 |website=National Institute of Korean History}} Sin (新) has both meaning of "New" and "Silla", thus literally means New Silla Province.

In 568, Jinheung Taewang made another royal visit to the northern border, visited Hanseong, and stayed in Namcheon on his way back to the capital. During his stay, he set Jinheung Taewang Stele, abolished Bukhansan Province, and established Namcheon Province ({{Korean|hangul=남천주|hanja=南川州|labels=no|lit=South River Province}}), appointing the city as the provincial capital.{{Cite web |title=Samguk Sagi Silla Jinheung 45 |url=https://db.history.go.kr/item/oldBookViewer.do?levelId=sg_004_0040_0450 |website=National Institute of Korean History |access-date=22 January 2023 |archive-date=22 January 2023 |archive-url=https://web.archive.org/web/20230122045941/https://db.history.go.kr/item/oldBookViewer.do?levelId=sg_004_0040_0450 |url-status=live }} Based on the naming system, the actual name of Han River during this time was likely Namcheon (Nam River) itself or should have the word ending with "cheon" ({{Korean|hangul=천|hanja=川|labels=no}}) not "gang" ({{Korean|hangul=강|hanja=江|labels=no}}) nor "su" ({{Korean|hangul=수|hanja=水|labels=no}}). In addition, "Bukhansan" Jinheung Stele clearly states that Silla had possession of Hanseong (modern day Pyongyang), thus Bukhansan has to be located north of Hanseong.

In the 11th century Goryeo, which succeeded Unified Silla, built a summer palace in Seoul, which was referred to as the "Southern Capital".

Seoul became the planned capital of Korea by Yi Seong-gye, the founding father of the Joseon dynasty. After enthroning himself as King at the capital of old Goryeo in 1392, Yi Seong-gye changed the name of his Kingdom from Goryeo to Joseon in 1393 and began his search for a place for a new capital. After several governmental debates, Yi Seong-gye chose Hanyang (Sindo) instead of Muak in September 1394. As Joseon's new capital, Hanyang was planned as a geographic embodiment of Korean Confucianism. Construction of the city began in October 1394. During its early construction stages, some major palaces, including Gyeongbokgung, were finished in 1395. The Fortress Wall surrounding Hanyang was partially finished around 1396.{{cite book |author1=김기호 |url=https://lib.seoul.go.kr/search/detail/CATTOT000001524017 |title= |author2=김웅호 |author3=염복규 |author4=김영심 |author5=김도연 |author6=유승희 |author7=박준형 |date=2021-11-30 |publisher=Seoul Historiography Institute |isbn=9791160711301 |location=Seoul |language=ko |script-title=ko:서울도시계획사 1 현대 이전의 도시계획 (서울역사총서 12) |trans-title=History of urban planning in Seoul, Vol. 1., Urban planning before contemporary age}}{{rp|96–111}}

The city of Hanyang was governed by the {{ill|Hanseongbu|ko|한성부}} ({{Korean|한성부|hanja=漢城府|labels=no}}), an agency of the national government dedicated to affairs on the administration of the capital city. The Hanseongbu divided Hanyang into two major categories: areas inside the Fortress Wall, which were typically named Seong-jung ({{Korean|성중|hanja=城中|labels=no}}) or Doseong-an ({{Korean|도성 안|labels=no|lit=Inside the fortress}}), and areas 10 Ri (Korean mile) around the Fortress Wall, which were named as Seongjeosimni ({{Korean|성저십리|hanja=城底十里|labels=no|lit=10 Ris around the fortress}}).

After Gojong's proclamation of Korea as the Korean Empire in 1897, Seoul was temporarily called Hwangseong ({{korean|hangul=황성|hanja=皇城|lit=the imperial city|labels=no}}). Much of modern development around this era was propelled by trade with foreign countries like France and the United States. For example, the Seoul Electric Company, Seoul Electric Trolley Company, and Seoul Fresh Spring Water Company were all joint Korean–U.S. owned enterprises.{{cite book |author=Chung |first=Young-Iob |url=https://archive.org/details/koreaundersiege10000chun |title=Korea under Siege, 1876–1945 : Capital Formation and Economic Transformation |publisher=Oxford University Press |year=2006 |isbn=9780198039662 |page=[https://archive.org/details/koreaundersiege10000chun/page/70 70] |url-access=registration}}

After the annexation treaty in 1910, Japan annexed Korea and renamed the city Gyeongseong ("Kyongsong" in Korean and "Keijō" in Japanese). The city saw significant transformation under Japanese colonial rule. Imperial Japan removed the city walls, paved roads, and built Western-style buildings.

Seoul was deprived of its special status as the capital city and downsized under imperial Japan, compared to the traditional notion among people of the Joseon dynasty that Seoul included the area of approximately {{convert|4|km|mile|sp=us|abbr=on}} radius surrounding the Fortress Wall (i.e., Seongjeosimni; {{Korean|hangul=성저십리|hanja=城底十里|labels=no}}). On October 1, 1910, Imperial Japan demoted Seoul as no different than any other city within the Gyeonggi Province. After Imperial Japan's redistricting, Seoul only included the area inside the Fortress Wall and present-day Yongsan District. In the 1930s, as part of Imperial Japan's war efforts leading up to the Second Sino-Japanese War, Yeongdeungpo District was annexed into Seoul on April 1, 1936, to function as an industrial complex for steel and other metalworking factories.

The city was liberated by U.S. forces at the end of World War II.

In 1945, following the liberation from Japanese colonial rule, the American military assumed control of Korea, including its capital city, then referred to as Kyeongseongbu in line with Japanese nomenclature. The U.S. military government published the Charter of the City of Seoul in the official gazette on October 10 of the following year. The charter declared Seoul as the name of the city and established it as a municipal corporation. Seoul's status as a municipal corporation mirrored the independent cities in the United States that do not belong to any county, and Seoul was established as an independent administrative unit, separate from the existing provinces.{{cite web |language=ko|date=2021-08-26|script-title=ko:서울은 어떻게 '특별시'가 됐나…근거 문서 '서울시헌장' 공개|url=https://history.seoul.go.kr/bbsctt/view.do?bbscttSn=2212200396&key=2210200045|website=Seoul Historiography Institute}} The Korean version of the Charter translated "municipal corporation" as "special free city" ({{Korean|hangul=특별자유시||hanja=特別自由市|labels=no}}),{{efn|As written in the Korean version of the charter: {{Blockquote|text=第一條 「京城府」를「서울市」라稱하고此를特別自由市로함|source=Official Gazette, USAMGIK Charter City of Seoul}}}} which later became special metropolitan city (or special metropolitan city; {{Korean|hangul=특별시|hanja=特別市|labels=no}}) in the {{ill|Local Autonomy Act of 1949|ko|대한민국 지방자치법}}.{{cite web |author=정 |first=현수 |date=2021-09-12 |title= |script-title=ko:번역이 만든 '서울특별시'…서울은 어떻게 '특별한' 시가 됐나 |url=https://news.mt.co.kr/mtview.php?no=2021091211392562588 |website=Money Today |language=ko}} Seoul has retained its status as the only special metropolitan city in South Korea.{{cite web |author=최 |first=현영 |date=December 3, 2002 |title= |script-title=ko:서울특별시, 광역시로 변경해야 |url=https://www.ohmynews.com/NWS_Web/View/at_pg.aspx?CNTN_CD=A0000096899 |access-date=June 28, 2024 |publisher=OhmyNews |language=ko}}{{Unreliable source?|reason=See unreliable sources list on WP:KO/RS|date=November 2024}}

During the Korean War, Seoul changed hands between the Soviet- and Chinese-backed North Korean forces and the American-backed South Korean forces four times: falling to the North Koreans in the June 1950 First Battle of Seoul, recaptured by UN forces in the September 1950 Second Battle of Seoul, falling to a combined Chinese-North Korean force in the January 1951 Third Battle of Seoul, and finally being recaptured once more by UN forces in Operation Ripper during the spring of 1951.{{Cite web |title=The Korean War Chronology |url=https://history.army.mil/reference/korea/kw-chrono.htm |access-date=6 September 2023 |website=U.S. Army Center of Military History |archive-date=9 September 2023 |archive-url=https://web.archive.org/web/20230909160307/https://history.army.mil/reference/Korea/kw-chrono.htm |url-status=dead }}{{Cite web |title=Chapter XXVI: The Capture of Seoul |url=https://history.army.mil/books/korea/20-2-1/sn26.htm |access-date=6 September 2023 |website=U.S. Army Center of Military History |archive-date=7 February 2023 |archive-url=https://web.archive.org/web/20230207134826/https://history.army.mil/BOOKS/KOREA/20-2-1/sn26.htm |url-status=dead }} The extensive fighting left the city heavily damaged after the war. The capital was temporarily relocated to Busan. One estimate of the extensive damage states that after the war, at least 191,000 buildings, 55,000 houses, and 1,000 factories lay in ruins. In addition, a flood of refugees had entered Seoul during the war, swelling the population of the city and its metropolitan area to an estimated 1.5 million by 1955.{{cite book|url=https://books.google.com/books?id=8GSpAgAAQBAJ|title=Planning Asian Cities: Risks and Resilience|page=159|publisher=Routledge|year=2012|editor=Stephen Hamnett, Dean Forbes|isbn=9781136639272|access-date=9 November 2015|archive-date=25 January 2016|archive-url=https://web.archive.org/web/20160125042515/https://books.google.com/books?id=8GSpAgAAQBAJ|url-status=live}}

Following the war, Seoul began to focus on reconstruction and modernization. As South Korea's economy started to grow rapidly from the 1960s, urbanization also accelerated and workers began to move to Seoul and other larger cities. In 1963, Seoul went through two major expansions that established the shape and size of the present-day Seoul—barring minor adjustments to the borders later in 1973 and 2000. In August 1963, Seoul annexed parts of Yangju-gun, Gwangju-gun, Siheung-gun, Gimpo-gun, and Bucheon-gun, expanding the northeastern borders of Seoul. In September, Seoul again annexed present-day Gangnam.{{cite web |script-title=ko:서울의 역사 |url=https://www.seoul.go.kr/seoul/history.do |website=Seoul Metropolitan Government |language=ko |access-date=31 December 2023 |archive-date=31 December 2023 |archive-url=https://web.archive.org/web/20231231041958/https://www.seoul.go.kr/seoul/history.do |url-status=live }}{{cite web|url=http://spp.seoul.go.kr/cms/board/Download.jsp?fileId=IUAjJDMyMTY1LS0kJA==|title=Urban Planning of Seoul|publisher=Seoul Metropolitan Government|format=PDF|year=2009|access-date=7 February 2014|archive-date=25 January 2016|archive-url=https://web.archive.org/web/20160125042517/http://spp.seoul.go.kr/cms/board/Download.jsp?fileId=IUAjJDMyMTY1LS0kJA==|url-status=live}} The two consecutive expansions more than doubled the size of Seoul from approximately {{convert|268|km2|mi2|sp=us|abbr=on}} to {{convert|613|km2|mi2|sp=us|abbr=on}}.{{cite web |script-title=ko:면적과 인구밀도 |url=https://data.si.re.kr/data/%EC%A7%80%ED%91%9C%EB%A1%9C-%EB%B3%B8-%EC%84%9C%EC%9A%B8-%EB%B3%80%EC%B2%9C-2003/374 |website=data.si.re.kr |publisher=서울연구데이터서비스 |access-date=31 December 2023 |archive-date=31 December 2023 |archive-url=https://web.archive.org/web/20231231041958/https://data.si.re.kr/data/%EC%A7%80%ED%91%9C%EB%A1%9C-%EB%B3%B8-%EC%84%9C%EC%9A%B8-%EB%B3%80%EC%B2%9C-2003/374 |url-status=live }}

After annexation, Gangnam's development was spurred by key infrastructure projects: the construction of the Hannam Bridge (1966–1969) and Gyeongbu Expressway (1968–1970). As Seoul's population kept growing, Park's regime focused its development plans on Gangnam. The main hurdle for Gangnam's development was floods because the area is low-lying and prone to flooding. Then Seoul mayor Kim Hyun-ok ordered construction of an expressway that doubled as embankment, which became the present-day Gangbyeon Expressway. The construction started in March 1967 and completed in September of the same year. Similar projects transformed previously flood-prone areas into usable land for development. Such areas include the current Ichon-dong, the Banpo apartment complex, Apgujeong-dong and Jamsil-dong.

Seoul was the host city of the 1986 Asian Games and 1988 Summer Olympics as well as one of the venues of the 2002 FIFA World Cup.

South Korea's 2019 population was estimated at 51.71 million, and according to the 2018 Population and Housing Census, 49.8% of the population resided in the Seoul metropolitan area.

There are four main mountains in central Seoul: Bugaksan, Inwangsan, Naksan and Namsan. The Seoul Fortress Wall, which historically bounded the city, goes over these mountains. The city is bordered by eight mountains, as well as the more level lands of the Han River plain and western areas.

Seoul has a large quantity of parks. One of the most famous parks is Namsan Park, which offers recreational hiking and views of the downtown Seoul skyline, especially via its N Seoul Tower. Seoul Olympic Park, located in Songpa District and built to host the 1988 Summer Olympics, is the largest park. The areas near the stream Tancheon are popular for exercise. Cheonggyecheon also has spaces for recreation. In 2017 the Seoullo 7017 Skypark opened, spanning diagonally overtop Seoul Station.

There are also many parks along the Han River, such as Ichon Hangang Park, Yeouido Hangang Park, Mangwon Hangang Park, Nanji Hangang Park, Banpo Hangang Park, Ttukseom Hangang Park and Jamsil Hangang Park. The Seoul National Capital Area also contains a green belt aimed at preventing the city from sprawling out into neighboring Gyeonggi Province. These areas are frequently sought after by people looking to escape from urban life on weekends and during vacations.

In January 2024 Seoul Metro, whose passengers at the time numbered approximately 7 million a day, announced plans for extensive pollution reduction measures across the network. The target was to cut pollution to over 30% below the legal limit of 50 μg/m3. It was 32 μg/m3 by 2026. The outset actuality was 38.8 μg/m3 average concentration of pollution.  Starting in 2024, ₩100 billion annually for three years was earmarked for air pollution reduction measures. These included installation of air conditioning, better ventilation systems and filters, replacement of dust-inducing gravel rail tunnel beds with concrete ones, dust-capture matting at turnstiles, and constant public readings for pollution within the system.{{Cite web |date=2024-01-16 |title=Seoul Metro initiates plans to reduce air pollution by over 30% - |url=https://english.seoul.go.kr/seoul-metro-initiates-plans-to-reduce-air-pollution-by-over-30/ |access-date=2024-09-01 |website=Official Website of the |language=en-US}}

Seoul has many historical and cultural landmarks. In Amsa-dong Prehistoric Settlement Site, Gangdong District, neolithic remains were excavated and accidentally discovered by a flood in 1925.{{cite web |url=http://english.visitkorea.or.kr/enu/SI/SI_EN_3_1_1_1.jsp?cid=264111 |title=Amsa-dong Prehistoric Settlement Site |publisher=Korea Tourism Organization |access-date=12 February 2014 |archive-date=22 February 2014 |archive-url=https://web.archive.org/web/20140222135311/http://english.visitkorea.or.kr/enu/SI/SI_EN_3_1_1_1.jsp?cid=264111 |url-status=live }}

Urban and civil planning was a key concept when Seoul was first designed to serve as a capital in the late 14th century. The Joseon dynasty built the "Five Grand Palaces" in Seoul—Changdeokgung, Changgyeonggung, Deoksugung, Gyeongbokgung and Gyeonghuigung—all of which are located in the Jongno and Jung Districts. Among them, Changdeokgung was added to the UNESCO World Heritage List in 1997 as an "outstanding example of Far Eastern palace architecture and garden design". The main palace, Gyeongbokgung, underwent a large-scale restoration project.{{cite web|url=http://www.royalpalace.go.kr/html/eng/data/data_01.jsp?dep1=2&dep2=1|title=About the Palace|publisher=Gyeongbokgung Palace|access-date=12 February 2014|url-status=dead|archive-url=https://web.archive.org/web/20080614221413/http://www.royalpalace.go.kr/html/eng/data/data_01.jsp?dep1=2&dep2=1|archive-date=14 June 2008}} Seoul has been surrounded by walls that were built to regulate visitors from other regions and protect the city in case of an invasion. Pungnap Toseong is a flat earthen wall built at the edge of the Han River, which is widely believed to be the site of Wiryeseong. Mongchon Toseong is another earthen wall built during the Baekje period that is now located inside the Olympic Park.{{cite web |title=Pungnap-toseong (Earthen Ramparts) |url=http://m.visitseoul.net/en/m/article/article.do?_method=view&m&p=02&menu=0004003002017&art_id=535&searchLoca&searchTheme=0002000001003&flag&searchType |url-status=dead |archive-url=https://archive.today/20140222005911/http://m.visitseoul.net/en/m/article/article.do?_method=view&m&p=02&menu=0004003002017&art_id=535&searchLoca&searchTheme=0002000001003&flag&searchType |archive-date=22 February 2014 |access-date=7 February 2014 |publisher=Seoul Metropolitan Government}} The Fortress Wall of Seoul was built early in the Joseon dynasty for protection of the city. After many centuries of destruction and rebuilding, about {{frac|2|3}} of the wall remains, as well as six of the original eight gates. These gates include the south gate Namdaemun and the east gate Dongdaemun.
