북한산 비봉(Bibong Peak of Bukhansan Mountain)
Bibong Peak, the core peak of Bibong Ridge, is only 560m high, but it is difficult to climb because it consists of huge rock walls.
In particular, at the top, there is a monument to King Jinheung, which is estimated to have been built around 555. It is surprising how they came up to here and erected a tombstone when the equipment was not developed.
