    A secret entrance, called ammun in Korean, was an emergency passage used to bring supplies and food into the fortress, without being noticed by the enemy.
    In Hwaseong Fortress, there were a total of five secret entrances.


    The Northern Secret Entrance was built on high ground, and stone staircases were built both inside and outside. All secret entrances in the fortress are built of brick, but here, bricks were also used for the walls on each side of the entrance. These brick walls have maintained their original structure built in 1796, and the entrance was repaired in 1972.
