Geumjeongsanseong (Geumjeong Mountain Fortress), Busan

Geumjeong Mountain Fortress stands proudly as the largest mountain fortress in the Republic of Korea. This fortress, with its historical significance and strategic location, has played a crucial role in safeguarding the region against external threats, particularly those originating from the sea.

The fortress's establishment traces back to a period marked by external invasions, including the Japanese invasion of 1592 and the Manchu invasions of 1627 and 1637. In the aftermath of these events, heightened awareness of the necessity for national defense prompted the construction of Geumjeong Mountain Fortress. King Sukjong, in the 29th year of his reign (1703), authorized the construction of this monumental fortress to fortify the coastal region against potential sea-borne attacks.

Geumjeong Mountain Fortress boasts a formidable architectural design, utilizing natural stones for the construction of both inner and outer walls. While the primary material is natural stone, weak sections of the fortress were reinforced with meticulously crafted square stone blocks. The walls, stretching approximately 17 kilometers in length, vary in height from 1.5 to 3 meters, creating a substantial barrier against potential invaders. The enclosed area, protected by these formidable walls, spans approximately 8.2 square kilometers.

Perched on Geumjeongsan, the fortress benefits from an elevated position, providing a strategic advantage for defense purposes. The elevated terrain enhances visibility and control, allowing the fortress to effectively monitor and respond to any potential threats from the sea.

Beyond its practical function as a defensive stronghold, Geumjeongsanseong holds immense cultural and historical significance. Visitors can explore the intricate details of the fortress, gaining insights into the challenges faced by its builders and the historical context that shaped its existence.
