The site of a bridge over the Taedong River built in front of the Anhak Palace, a royal palace of Koguryo (BCE 277-CE 668), is the remains of a big wooden bridge, which linked the present-day Chongho-dong, Taesong District with Hyuam-dong, Sadong District in Pyongyang.

   The framework of the bridge was built mainly with rectangular timbers 38cm wide and 26cm thick.

   Guardrails were placed at the entrance and along the edges for the safety of pedestrians.

   All connections were tightly interlinked without using any metallic joints such as nails or clamps. This shows that the Koguryo people knew that it was more superior to link parts of wooden structure to be exposed to water by dovetailing rather than using metallic joints.

   The bridge had some auxiliary facilities such as a lamp post.

   Such a big wooden bridge was quite rare in the world at that time.

   The site, together with the Walled City of Pyongyang, Anhak Palace, Jongnung Temple and mural tombs, showcases the developed architecture of Koguryo.
