Pyongyang (Goguryeo Capital)
Core idea
Riverine Goguryeo capital pairing a walled flatland palace with a mountain refuge fortress, later replanned as Jangan-seong
Why it matters
A key stage in Korean walled-capital planning, from palace-and-fortress pairing to a fully planned city
Description
In 427 King Jangsu moved the Goguryeo capital from the mountainous Gungnae fortress to Pyongyang on the Taedong River. The royal seat, the Anhak Palace, was a square walled compound roughly 622 m on each side, laid out with gardens, artificial hills and lakes, set at the foot of Mount Taesong, whose hill-fortress of some 7 km circumference provided refuge above it, a classic Goguryeo pairing of flatland palace and mountain stronghold. During the sixth century Goguryeo built Jangan-seong, a fully planned multi-walled walled-city capital integrating palace, government and residential quarters, to which the court relocated in 586 and which served until 668.
Significance
The move to Pyongyang marked Goguryeo's shift from a defensive mountain capital to a riverine metropolitan one at the height of the kingdom's power, recasting the seat of the state as a centre of administration rather than mere refuge. The later Jangan-seong is among Korea's earliest fully planned urban fortress-capitals, integrating palace, administration and residence within multiple walls and informing the design of subsequent Korean city-fortresses.
What became of it
Established as the Goguryeo capital in 427 CE with the Anhak Palace and a paired mountain refuge fortress; the centre later shifted south-west to the walled Jangan-seong (from 552/586), and the sites now survive as archaeological remains in modern Pyongyang.
