The name Hwahongmun translates to 'Rainbow Gate,' referring to the colorful mist created by water flowing through the seven arches.
The pavilion atop the gate was historically used for military lookouts, housing soldiers who monitored the stream and the northern approach.
It is built with a sophisticated sluice system using iron gates that could be lowered to block invaders or debris during floods.
The structure is made of granite, reflecting the architectural transition period of the late 18th century.
It survived the Korean War with only partial damage, despite the destruction of much of the surrounding fortress walls.
The design was influenced by the 'Seonggwe-uigo' (Treatise on Fortress Construction), which applied advanced military engineering principles of the time.
Hwahongmun, also known as Buksumun, is the northern sluice gate of the Hwaseong Fortress, constructed between 1794 and 1796 during the Joseon Dynasty. It functions as a seven-arched bridge built over the Suwoncheon Stream, designed to regulate water flow for the city. The structure is distinguished by its stone base topped with a wooden pavilion, which was originally used as a defensive observation point. It is one of the few water gates of its era still standing in South Korea. The structure's design allowed for the drainage of water during heavy rains while maintaining the integrity of the fortress walls. It serves as a critical component of the UNESCO World Heritage-listed Hwaseong Fortress defensive system.
