The Seoul Metropolitan Government has launched a new guided walking program to explore Tangchundaeseong—a historic Joseon-era fortress known as the “fortress made by heaven.”
The tours will run twice a month, on the second and fourth Sundays, until November.
Tangchundaeseong connects Hanyangdoseong (the Seoul City Wall) to Bukhansanseong, forming a critical part of the capital’s old defense system.
Constructed between the reigns of Kings Sukjong and Yeongjo over 39 years, it follows the ridge between Inwangsan and Bukhansan, using the natural terrain for strategic advantage.
The 2-hour tour begins at Changuimun Gate, moves through Seongbulsa Temple, and ends at Hongjimun Gate.
Visitors will see remnants of stone walls, old military posts, and inscriptions from the Joseon dynasty.\
Registration is via Seoul’s public reservation site (yeyak.seoul.go.kr). Each session is limited to 15 adults, and hiking shoes are required due to rugged terrain.
