South Korean architecture refers to any architecture in South Korea, which includes architecture from Neolithic–7th century (B.C.E.), three-kingdoms of Korea, Goryeo, Joseon, Japanese occupation, Korean War, and modern architecture. Historic architecture Located in Seoul is the Gwangtonggwan, the oldest continuously-operating bank building in Korea. It was registered as one of city's protected monuments on March 5, 2001. Joseon Architecture Post-division architecture American models heavily influenced new Korean buildings of any importance, with domestic architecture both civil and rural keeping to traditional buildings, building techniques, and using local materials, and local vernacular styles. The pragmatic need to rebuild a country devastated by exploitative colonization, then a civil war, led to ad hoc buildings with no particular styles, extended repeatedly, and a factory system of simple cheap expendable buildings. As few Korean cities had a grid-system, and were often given limits by mountains, few if any urban landscapes had a sense of distinction; by the mid-1950s, rural areas were underfunded, urban areas overfilled, and urban sprawl began with little money to build distinctive important buildings. Buildings were built as quickly as money and demand would allow in a workman-like anonymous way, but without individual identities. Architects were almost to a man trained in the United States, and brought American design, perspective, and methods without much recourse to the local community look and feel. As the need for housing for workers increased, traditional hanok villages were razed, hundreds of simple cheap apartments were put up very fast, and bedroom communities on the periphery of the urban centres grew, built and financed as company housing. Little effort was made to have a sense of an architectural aesthetic. This urgency for simple fast housing left most Korean downtowns faceless, consisting of rows and rows of bland concrete towers for work or living and local neighborhoods rebuilt with cheap materials. Little or no attempt was made for planning, if planning had been possible. In the countryside, traditional building continued. Well into the 1980s, Korea had architecture, but its buildings had little aesthetic, a limited sense of design, and did not integrate into the neighbourhoods or culture. Awareness that functionality had reached its limits came quickly as Korea moved into the world through sports culture. Sports architecture transited to a Korean style. Sports architecture South Korea won the 1986 Asian Games and the 1988 Olympic games, which spurred waves of new building activity. To market the country
