Haemieupseong

Haemieupseong is a historic fortress in Seosan with stone walls, multiple gates, and watchtowers built according to traditional Korean military architecture. The site spreads across extensive grounds and displays the defensive structures that protected the region centuries ago.

The fortress was built between 1417 and 1421 during the Joseon Dynasty as a military command center against naval attacks. It later served as a defensive stronghold during periods of conflict and upheaval in the region.

The fortress grounds contain significant religious history as the location where approximately 1,000 Roman Catholics faced martyrdom during persecution periods.

The site is accessible from early morning until late evening and offers various areas to explore, including open pathways and elevated sections. Comfortable shoes are recommended as the terrain features uneven surfaces and slopes.

Visitors can participate in traditional Korean activities such as archery and wrestling within the fortress grounds, bringing ancient practices to life. These hands-on experiences connect the past directly to modern visitors.
