Paldalmun is the southern gate to Hwaseong Fortress, serving as the access point to Suwon from the south.
During the Joseon Dynasty, it was the gateway to Hyeollyungwon, the tomb of Prince Sado, used by Jeongjo, his son, and other kings. Construction began on February 28, 1794, and was completed on September 15 of the same year. The name "Paldalmun" means „a gate open to all directions“.
This gate, which faithfully preserves its original appearance, was designated as Treasure No. 402. An Ongseong, a semicircle-shaped defensive outwork,
encircles Paldalmun.
