Unhwa-ri Fortress Site

This fortress is a valley-enclosing mountain fortress (pogok-sik sanseong), built to take in, within its walls, a peak (270 m) on the eastern ridge of Daeunsan Mountain (742 m above sea level) along with the ridges and valley below it. The fortification wall is heavily damaged to the north but survives in good condition to the south-east. The walls were made by shaping natural stones: in steep areas using the naetak method (building the outer face as a stone wall while filling the inside with rubble and earth), and on gentler slopes using the hyeopchuk method (building both the inner and outer faces as near-vertical stone walls). The wall runs for about 1 km and stands 100–220 cm high. Inside the fortress a round stone platform, built of roughly dressed natural stones, survives, though its exact purpose is not known in detail. Judging from the pottery fragments found within the fortress and from the adjoining Unhwa-ri tomb cluster below it, the fortress is presumed to have been in use from the Silla period through to the Joseon period.
