A coastal fortress with more than one job
In Jeongjuk-ri, Geunheung-myeon, Taean, Anheungseong is also known as Anheungjinseong. In the Joseon era it helped guard sea approaches and escort vessels transporting goods for the state. The challenging waters of Korea's west coast give context to why this location mattered.
Why both 1583 and 1655 appear in its history
The Academy of Korean Studies explains that a historic text records construction in 1655, while an inscribed stone found at the site points to 1583. Researchers distinguish the earlier initial construction from later repairs or rebuilding. Rather than choosing one date without context, think of a fortress adapted across generations.
What the remains can tell you
The scholarly entry gives the wall circuit as approximately 1,714 metres and identifies surviving structures near the south gate as valuable evidence. That figure describes the historic wall, not a verified walkable trail. Observe the masonry and terrain from permitted areas, respecting heritage protection and any temporary barriers.
Plan responsibly
The listed heritage location is Jeongjuk-ri 1155-1, Geunheung-myeon, Taean-gun (태안 안흥성). It is not a verified car park or entrance. For November 2026, current opening, accessible sections, admissions, parking and transit have not been confirmed. Check Taean visitor information before departing.
