Although it contains several low peaks, the land of Apo-eup also contains a great deal of flat and fertile floodplain; local agriculture is dominated by rice cultivation.
[1] The region first enters historical records in the Proto–Three Kingdoms period, when it successfully rebelled against the local polity of Gammun-guk.
It appears as part of Unified Silla in 757, when it made up two myeon in Gaeryeong-hyeon: Dong-myeon and Apo-myeon.
This situation continued for more than a thousand years, until the massive reorganization of Korea's local governments in 1914, at which time the two myeon were united into the present-day entity of Apo-eup.
Local attractions include the ancient tombs of Bongsan-ri, which are located in the floodplain of the Gamcheon.
