Potongmun (Korean: 보통문; lit.

Potong Gate) is the western gate of the inner system of the walled city of Pyongyang (Pyongyang Castle).

It was originally built in the sixth century [1] as an official Koguryo construction, and was later rebuilt in 1473.

It features a granite base topped by a two-story structure.

The gate's structure was destroyed by American air attacks during the destruction of Pyongyang in Korean War, but was later reconstructed in 1955.
