The North Gate of Geumjeongsanseong Fortress is located 1.6 km west of Beomeosa Temple, at the spot where the main ridge, descending southward from Godangbong Peak, rises again toward Wonhyobong Peak. The North Gate exhibits the crudest appearance of the four gates of Geumjeongsanseong Fortress, has no arch-shaped decoration and is smaller than the other gates. The upper part of the foundational facility, measuring one kan (a unit of measurement referring to the distance between two columns) at the front and one kan at the sides, is a one-story watch tower with a half-hipped roof with a double-wing bracketing system. The gate measures 2.5 meters at the front, and 3.5 meters at the sides. The area around Sesimjeong Pavilion, situated in front of the gate, used to be known as 'Hwaeombeol' because the venerable Korean Buddhist priest Wonhyo (617-686) preached the Hwaeomgyeong, or Avatamsaka Sutra, there.
It was also a training camp for monk-soldiers, including Buddhist monks from Beomeosa Temple, Gukcheongsa Temple, and Haewolsa Temple. The North Gate is known to be the passageway used by independence activists when they carried the Korean Declaration of Independence and the documents related to the independence movement and the March 1st Movement in 1919 at Beomeosa Temple, got off at Mulgeum Station on the Gyeongbu Line, by crossing Godangbong Peak of Geumjeongsan Mountain, and went to the Cheongnyeonam Hermitage.
