Seoul City Wall (Hanyang Doseong)
Walk the ridge that defined a capital city for five centuries — the same line that separated "inside Joseon" from everything else.

Built from 1395 by King Taejo to enclose Hanseong, this wall still rings Downtown Seoul and still works as a cultural boundary. Parts survived Japanese colonial demolition and two major invasions, making the surviving stretches in Jongno and Jung districts a rare layered record of the entire Joseon period.
What to look for
- The shift in stonework: original sections use medium round stones bound in mud; Sejong the Great's 15th-century refurbishment replaced the earthen sections with rectangular stone blocks — you can spot the seam where earthen construction gave way to cut stone
- Gaps where gates once stood, most notably the missing Seodaemun (west gate), torn down by the Japanese colonial government during modernization
- The Eight Gates framework — look at the map before you walk to understand which gate anchored which cardinal direction
The wall survives primarily in the Jongno and Jung districts; pick up the trail at any surviving gate and follow the ridge path between them.
