A variety of
Paleolithic relics have been discovered at Jeongok-ri, first in 1978. Since 1993 the Yeoncheon Jeongok-ri Paleolithic Festival has celebrated the discovery. Yeoncheon was the site of the
Battle of Yultong during the
Korean War, where the
Philippine 10th Battalion Combat Team defended their position during the
First Chinese Spring Offensive. In August 1980, shortly after the 1980 coup, the military regime of
Chun Doo-hwan established a
concentration camp for "purificatory education" in Yeoncheon. In August 2015, over 100 civilians were evacuated from the area after North and South Korea exchanged artillery fire. ==Administrative districts==
