Deungju

Tŭngju, later known as Anbyŏn, lies in the northeastern Korean country near the head of Yŏnghŭng Bay. Under Koryŏ it formed part of the eastern frontier's system of roads and stations. In 1018 the Anbyŏn protectorate was transferred here from Hwaju, making the town an important administrative centre. The surrounding district also held the tomb of an ancestor of Yi Sŏnggye, the future founder of Joseon.
