Taedongmun, City gate in Chung-guyok, North Korea.

Taedongmun is the eastern gate of Pyongyang's inner castle, with a granite base pierced by an arched passage and topped by a two-story wooden pavilion, the Euphoru. The pavilion holds two hanging plaques: "Taedong Gate" on the first storey and "Upho Pavilion" on the second.

The gate was built in the sixth century as part of Koguryo fortifications and suffered severe damage during the Imjin Wars. The structure visible today was fully rebuilt in 1635 following this destruction.

The gate's two plaques name it: "Taedong Gate" on the first storey, calligraphed by Yang Sa-on, and "Upho Pavilion" on the second, written by Pak Wi. The pavilion's name refers to its view over the Taedong River. From Goguryeo to Joseon a ferry crossed the river just outside the gate.

The gate is easy to locate at the eastern access to the inner castle and can be seen from various points in the city. The best time to visit is during daylight when light conditions clearly reveal the granite details and wooden pavilion.

The gate was saved from demolition under Japanese rule because a 1909 survey graded it B, meaning high architectural value and special protection; five other gates in Pyongyang were removed in 1907. In 1923 the surrounding area became a park, and the Chilcheung Stone Pagoda was moved in front of the gate.
