Sangdangsanseong is a historic hillside fortress east of Cheongju, rebuilt in stone in 1716 during the reign of King Sukjong. Explore the old walls, gates and the landscape of the settlement inside.
- Address
- 70 Seongnae-ro, Sangdang-gu, Cheongju, Chungbuk (municipal approach address); heritage site location: San 28-2, Sanseong-dong
- Nearby transit
- The fortress is outside central Cheongju, not directly next to a railway station. Check current buses, parking and gate access before travel.
- Hours
- Open-air fortress heritage site. A single opening schedule and entry price were not confirmed from the municipal detail page. Check any closures or restricted sections, especially near dusk or during bad weather.
Two Cheongju municipal sources give different location formats: San 28-2, Sanseong-dong for the monument itself and 70 Seongnae-ro as the approach address. Use the latter for navigation and confirm the entrance. Neither a fixed opening time nor a universal admission fee was verified for the outdoor heritage site.
Why go
Walk through the fortress gates and trace the surviving walls and terrain. Some stretches have slopes, steps or uneven ground and may not be accessible to every visitor.
