Haeju
Haeju stands near an inlet on Korea's western coast, a centre for the surrounding country of Hwanghae. Under Koryŏ it became the seat of officials administering the western province; by 1389 the provincial governor's headquarters were here. When Joseon reorganised the provinces in 1395, Haeju and P'ungch'ŏn supplied the name P'unghae. Haeju remained an administrative centre and grew into a substantial town in the later Joseon period.
