East Gate - Trace of Baekje's Earthen Fortification

At the East Gate of Gongsanseong, we can see traces from which the fortress was constructed. Gongsanseong today is a stone fortress. However, it was once an earthen fortress during the Baekje Period, but later was rebuilt with stones. An area near this East Gate was the only place left with traces of the earthen fortress that was built in the Baekje Period.

Exit the East Gate and look below to the right. You’ll see traces of the earthen fortress intact.

The soil was well packed and stacked according to a certain interval. This construction method allowed the fortress to withstand flood and external damages.

Tremendous manpower was needed to construct a fortress with this type of architecture. Based on such large scale public works, we can assume a powerful royal authority constructed this fortress.
