This flatland fortress, designated Historic Site No. 116, was constructed in the early Joseon Dynasty. Visitors can walk along the 1.8 km wall. The site carries deep historical significance as a persecution ground for Catholic believers in the late Joseon era. Reconstructed government offices and a prison are located inside the walls. The fortress hosts seasonal traditional performances and festivals.
Haemieupseong is a Joseon-era Korean fortress in what is now Haemi-eup, South Chungcheong Province, South Korea. Haemieupseong was built between 1417 and 1421 during the Joseon period. In January 1963, it was listed as South Korea's Historical Site No. 116 and was renovated in 1973. The castle served as a backdrop to the Donghak Rebellion in 1864. This fortress, originally built to protect against Japanese pirates, was a historical site at which thousands of Catholics were executed during the French Invasion in 1866.
