The north gate, which is located below the Banghwasuryujeong, is called Hwahongmun, which means “beautiful rainbow-colored gate.” It was constructed over a river by broadening Suwoncheon, which flows through the Hwaseong Fortress, and set up a bridge with seven holes. Above this gate, a multi-story building was erected. Hwahongmun played a role of a bridge, connecting villages from the either side of the river. A bower on the river was used as a resting area for the people and facilities were equipped with canons to protect the Fortress.
