The earliest evidence of human occupation in the Pohang area is from the Mumun Pottery Period (1500–300 BC). Archaeologists have unearthed small villages and megalithic burials (dolmen) from this period. Still a small fishing village at the dawn of the 20th century, the earliest steps toward developing Pohang into a place of greater significance were taken in 1930 with the construction of a modern harbour. Pohang grew rapidly afterward, attaining the designation of town ("eup") in 1931 and then earning the status of city ("si") in 1949.
