Upon arrival, they were tortured to death. In particular, approximately 1,000 people are recorded as having been executed during the persecution in 1866.

The plaza inside of the fortress has a prison site where Catholics were chained up under the Daewongun government, and a gigantic old tree which was the tree used for torturing. The stones which were used for thrashing are located outside of a fortress gate and have become a holy place.

Haemi Martyrdom Holy Ground is the site where nearly 1,000 Catholics in Chungcheongnam-do were buried alive during the time between the Byeongin Persecution in 1866 and 1882. At that time, Catholics were executed outside Haemieupseong Fortress' Seomun Gate (West Gate). As it was difficult to execute them one by one, the martyrs were buried alive in a big hole all at once. When confronted with their deaths, the martyrs prayed while singing 'Yesumaria' (Jesus Maria). Because it also sounds like "Yeosumeori", the place was called 'Yeosutgol' as well.

The 16-meter-high memorial tower was set set up near Haemicheon Stream to pay tribute to the nameless martyrs who were buried alive. Many Catholics visit this location every year to remember and honor the martyrs who sacrificed their lives for their belief.
