Pyongyang Castle

[1] In 427, Jangsu of Goguryeo transferred the Goguryeo capital from Gungnae Fortress (present-day Ji'an on the China-North Korea border) to Pyongyang Castle,[a][5][6] a more suitable region to grow into a burgeoning metropolitan capital,[7] which led Goguryeo to achieve a high level of cultural and economic prosperity.

[8] In 668, Pyongyang became the capital of the Protectorate General to Pacify the East established by the Tang dynasty of China.

Pyongyang was left abandoned during the Later Silla period, until it was recovered by Wang Geon and decreed as the Western Capital of Goryeo.

By 1880 it had more than 100 churches and more Protestant missionaries than any other Asian city,[9] and was called "the Jerusalem of the East".

[11] It was the site of the Battle of Pyongyang during the First Sino-Japanese War, which led to the destruction and depopulation of much of the city.
