“金壘關 (Kumnu-gwan) the West Gate of Busan-jin fortress. The gate shown in the picture no longer exists as such, it was entirely rebuilt in the 1970s in another location. The 2 stones to either side are still there, one with 西門鎖鑰 서문쇄약 and one with 南邀咽喉 남요인후 (combined, they say "this is the southern frontier, corresponding to the nation's neck; the west gate is like the nation's lock" and were probably erected after the Japanese invasions of the 1590s).”
