It is the gate in the heart of Taesongsan Funfair.
It was first built with the fort before Koguryo moved its
capital to Pyongyang. It was rennovated in September Juche
67(1978) without using timber. Though it was built with
cement, it resembles an old wooden building without nails.
The total height of the gate is 19.5m and the frontal side
of the pillar is 17.15m long and 6.3m wide.
