Pyongyang ( , , ) is the capital and largest city of North Korea, where it is known as the "Capital of the Revolution". Pyongyang is located on the Taedong River about upstream from its mouth on the Yellow Sea. According to the 2008 population census, it has a population of 3,255,288. Pyongyang is a directly administered city () with a status equal to that of the North Korean provinces. Pyongyang is one of the oldest cities in Korea. It was the capital of two ancient Korean kingdoms, Gojoseon and Goguryeo, and served as the secondary capital of Goryeo.

In the end, neither proposal was implemented. Prehistory In 1955, archaeologists excavated evidence of prehistoric dwellings in a large ancient village in the Pyongyang area, called Kŭmtan-ni, dating to the Jeulmun and Mumun pottery periods.
