Dongnae

Dongnae (actual Busan) is a port of Goreyo situated in the southern part of the kingdom, between a number of narrow valleys between the Nakdong River and Suyeong River.

Dongnae was first called Geochilsan-guk which existed in the second and 3rd and 4th centuries as a chiefdom of Jinhan. It was absorbed by Silla and renamed Geochilsan-gun. The word Geochilsan means rough mountain, probably referring to Hwangnyeongsan, located at the center of the city.

In 757, Geochilsan-gun was again renamed Dongnae, which it is still called.
