Changwon

The region has been inhabited since the Bronze Age, and its urban areas have been renamed and re-organized many times throughout history. In 1974, with the creation of the Changwon National Industrial Complex, the three historically interdependent cities of Masan, Jinhae District, and Changwon began to undergo significant economic development, growing into an important industrial centre. On 1 July 2010, the cities of Changwon, Jinhae, and Masan merged to form the current city of Changwon.

As Korea's first planned city, modeled after Canberra, Australia, Changwon uses accessible urban planning including many parks and separate residential and industrial areas. The city has also branded itself an "environmental capital" with the municipal government actively participating in climate change conferences and committing to the development of sustainable policies like the globally recognized bike-sharing program, Nubija.
