Horogoru derives its name from the local dialect, referring to the fortress being located on a 'narrow neck' of land.
The fortress occupies a triangular basalt cliff formed by ancient volcanic activity.
Excavations revealed a multi-layered structure indicating it was used by Goguryeo, Silla, and later, the Goryeo dynasty.
The location was part of a chain of fortresses built along the Imjin and Hantan Rivers to control the southern frontier.
A specialized Goguryeo-style roof tile called 'Chi-mi' was discovered here, which decorated the corners of high-status buildings.
The site was once a critical crossing point for armies moving between the Korean peninsula's northern and southern regions.
It is one of the few sites where Goguryeo-era stone stacking techniques can be observed in their original geographical context.
Yeoncheon Horogoru is a fortress ruin built during the Goguryeo Kingdom, situated on a basalt cliff overlooking the Imjin River. It served as a vital strategic defense point against the Silla Kingdom. The site features the remains of earthen ramparts and a stone wall structure restored to reflect the original Goguryeo architectural style. Archaeologists have excavated significant artifacts including roof tiles, iron arrowheads, and pottery from the site. The landscape is characterized by wide, open grasslands that emphasize the fortress's isolated position on the northern border. It is a designated historic site in South Korea. The area is integrated into the Yeoncheon Imjin River Biosphere Reserve.
