Abstract

The Deokjinsanseong Fortress(德津山城) in Paju is located on the norther coast of the Imjin river. Currently, five excavations have took place. These excavations have found that the Deokjinsanseong Fortress was first constructed by Goguryeo. It was subsequently improved several times during the Unified Silla period and was used until the late Joseon period in accordance with need. The characteristics of the wall of the fortress body was confirmed by the excavation to involve 1~3 chi, a western wall, and an outer fortress. These results show that the aspects of its construction method largely changed four times. Stage 1 involved the use of unprocessed crushed stones for the first wall which was constructed by Goguryeo, without laying them by floor. Clay was filled in between the fortress stones to strengthen its durability. Stage 2 involved layering coursed masonry layers by using polished rectangular fortress stones. Stage 3 involved layering coursed masonry layers by using square or rectangular fortress stones with all 4 sides polished and was carried out to reinforce the walls of stage 2. Stage 4 was layered in un-coursed masonry layers by using large crushed stones at the base and small crushed stones at the top. The change in construction method displayed a close association with the historical background of the Imjin river basin. During the mid-to-late 6th century, Goguryeo constructed stone walls to defend against Silla. Silla newly constructed stone walls while repairing the Deokjinsanseong Fortress as it went through the Silla-Tang War. It then added another wall to the repaired wall after the 8th century. The Deokjinsanseong Fortress seems to have been continuously managed as it grew in importance as Silla began strengthening its northern boundaries against Tang and Balhae. On the other hand, it stopped being used for a while in the Goryeo period but was used again in the Joseon period. The outer fortress, a wall constructed in the Joseon period, was constructed during the reign of Gwanghaegun(1623), as part of its repair. The Deokjinsanseong Fortress is extremely important in that it displays by itself the continuous changes of construction method spanning the Three Kingdoms period to the Joseon period. This allows researchers to understand the characteristics of fortress construction methods in each period and the fortress construction process, providing important archeological data for the research of fortress construction methods from the Three Kingdoms period to the Joseon period.
