Mountain gatehouse on a seventeenth-century wall so long that surveys disagree on its length.
This guide to Geumjeong Fortress's north gate near Busan opens with a discrepancy no one has resolved: surveys of the wall's length disagree by nearly three kilometers. It traces why, starting with construction from 1701, after two invasions convinced the Joseon court it needed a mountain stronghold, and the fortress's near-immediate problem of being too vast to defend with any garrison it could raise. You'll hear how the court split it in two with a second wall just to make it manageable, and how the gatehouse fared once soldiers stopped bothering to guard it at all. Stand at the gate and look at both directions of wall vanishing into the pines.
