The purpose of this study is to examine the archetype of the Gyeongju Castle walls and the facilities around it to bring together previous studies and identify the specific scale and structure of the archetype. The findings can be summarized as follows. First, we verified the exact location and dimensions of the castle through an over-lay of land registration maps from the Japanese colonial period, land registration maps from the present day, cadastral maps, and excavation records. Second, the dimension of the rampart and fort of the castle were discovered by combining and analyzing historical evidence, modern research data, historical site studies from the Japanese colonial era, and maintenance records. Third, the historical records related to the yeojang (rampart sub-wall) formats in the Joseon Dynasty were used to examine the archetype of the yeojang. This study led to the discovery of the archetype of the Gyeongju castle yeojang in the early stage of King Munjong's reign (1451), and the archetype created after the Japanese Invasion (16th century). And finally, although most of the rampart is not present, the structure of the castle can be estimated based on historical research, and research materials modern and contemporary(excavation conservation field survey). In addition, this study presented a archetype restoration plan for each site, to be used as foundational data for future restoration projects.

Our country traditionally employed a defensive system against the aggression by foreign powers by using a town castle and mountain castle. The moat was one of such a defensive system; however, there is few research work on a moat in comparison with its long history. This study was carried out to see the process of the changes of the Wolseong Fortress at Gyuongju, focused on the moat of the scale and nature of the construction methods to analyze such a Wolseong Fortress at Gyuongju as a result of consideration through bibliographical study, on-site investigation, and interviews, etc. This research discovered some facts as follows: the moats of Wolseong fortress at Gyeongju are roughly divided into three types; the first one is a natural moat flowing curved by the south side of Wolseong using the natural stream[Namcheon]as it is; the second one is a pond-type moat made by digging up plane non-rectangular pond along stereobate of castle wall with lakefront built with stream pebbles, and the last one is masonry moat at the east side of Wolseong with chisel-trimmed granites orderly piled in a plane triangular form. Among these, the pond-type moat was identified at the east-north-west side of Wolseong and the pond slopes from east to west as a separate one constructed with the terraces.

The purpose of this study is to re-exam of the modern values of a moat to utilize it with various functions such as a military defense on the outskirts of the castle, dividing the space by its boundary, controlling the micro-climate in the worsening modern environment with temperature rise due to climate change and habitat reduction of animals, and providing the habitat of animals to modern urban space, etc. The scope of the study is focusing on the castles with the moat installed to prevent the enemy from accessing directly to the wall using a pond or water path for military defense on the outskirts of the castle or to divide it into boundaries. In the Orient, the Nakan Eupseong, Haemi Eupseong, Gyeongju Wolseong in Korea and the Forbidden City in China, and Nijo Castle and Osaka Castle in Japan were selected. In the West, Edinburgh Castle in Britain, Blois Castle in France, Chillon Castle in Switzerland, and Frederiksborg Castle in Denmark were selected for the study. As a research method, literature research and field research were conducted. For the Orient, it was conducted in parallel with the literature research and field research. For the western, it was mainly conducted with literature research. For the literature research, the origin of the moat, the concept of the moat, the function of the moat, the history and culture of the western moat are based on the data from the related institutions and previous studies. For the Orient field research, exploring was conducted in two to three times from Jan. 2016 to Dec. 2016 in each of the target areas of Nakan Eupseong, Haemi Eupseong, Gyeongju Wolseong in Korea and the Forbidden City in China, and Nijo Castle and Osaka Castle in Japan. The contents of the research were analyzed through interviews, photographs, measurements, and observations on the function, size, and characteristics of the moat of each target. The results of this study are as follows. The moat was a structure installed to set a boundary for military defense facilities on the outskirts of a castle and it played an important role as a part of the city in the ancient times of Asia and the West through the Middle Ages. The role of the moat is gradually disappearing due to the disappearance of the purpose of military defense. However, moats are excluded from modern landscape planning, despite the fact that a moat filled with water is a hydrophilic space with great historical and cultural value such as various cultural activities and providing habitats for animals. By reflecting on the moats various functions in modern cities and utilizing it, it is expected to be utilized to bring pleasant air into the city where the circulation of air is blocked and energize the city as a hydroponic element.

This study grafts geophysics on modem archaeology and approaches with scientific and systematic methods to an excavation plan or archaeological study by means of GPR exploration which can assist archaeologists to study Wolseong fortress without excavating it. We investigated the areas in front of Seokbinggo (ice storage facility built of stone) and in the eastern corner of the castle with GPR. As a result, we detected 7 large squared building foundations, stone walls, an entrance for the fortress, many other foundation stones, a road and a garden.

Centering around ruins recognized of being relatively early stage related to flat tile and brick, excavated in Silla capital area, the study attempted elementary approach to seek the appearance time of every remain through comparing them from the excavated cases and production methods of Short beating, Medium beating plate, Long beating plate and Stamped-roof tile. Gyeongju began to use the short beating plate made of tile-less plates or tile plate and increased its quantity. That is deemed to be due to efficiency of beating plate making methods, and moreover to be limited only for use in the palace castle and offices. That is, making short beating plates is presumed to be made merely under some definite objectives. Medium beating plate has been spread to the whole country since Silla and Baekje united. Differently from Koguryo and Baekje, Silla had its unique Beating-plates making technology available for mass-production, which was spread to the whole country and resulted in disappearing of Koguryo and Baekje technology. Long beating plate was not nearly founded in Gyeongju area, but flat tile and common tile excavated in Sachunwang Temple site and Samrang Temple 3rd remains are known. In the outskirts of Gyeongju, long beating plate appeared between the latter half of 8C and the beginning of 9C. Until now, different views have raised to appearance of long beating plate of Unified Silla, which is expected to be clarified under the situation excavated by position relations. Stamped-roof title in Gyeongju is estimated as used after the datum point year 679. While in Baekje area, five stems and branches were involved, in Silla area, code or sign was shown much. The difference between two areas would be due to each other factory, and especially the marked contents werenot letters, which means it had been changed from Baekje s existing-methods. That is, it says the production environment changed owing to Silla's merging. And stamped-roof tile was temporarily used in Gyeongju but soon disappeared, which was because Silla beating plates made under cylinder-shaped tile barrel(圓筒瓦桶) and hitting-pressing of Medium beating plate had beenspread to the whole country, so the production technology of Koguryo and Baekje was naturally dismissed. In consequence, the mergence by Silla brought about unification of each nation's special technology.

From 1949 to the present day, many Koguryo sites have been excavated, in North Korea. It can also be said that archaeological surveys and studies in North Korea have triggered Koguryo archaeological studies in South Korea. However, since the 1990s, the excavation of Koguryo sites and archaeological research in North Korea has been carried out as an extension of Daedonggang culture. Therefore, these archaeological surveys focused on the Pyongyang and more general northwestern areas of North Korea, and the conclusion was that Koguryo was a powerful nation with a millennium-long history inherited Gojoseon. Beginning in 1945 in North Korea, the archaeological surveys and related systems were organized, and burial mounds, castles, and city remains were excavated under the idea that Koguryo was a millennium-long, strong nation. In addition, archaeological research has been conducted to validate and confirm this belief. On the notion that Koguryo was founded in 277 BCE, it was insisted that the age of the tombs in Pyongyang was increased and Pyongyang took the position as a Vice Capital in the 4^th Century. Recently an excavation of the castle located in Pyongyang supports the idea that Koguryo inherited Gojoseon on a layered basis. However, the archaeological and conceptual grounds for the founding of Koguryo in the 3^rd Century BCE or the succession of Gojoseon and Koguryo were insufficient. As can be seen from the reconstruction of the royal tombs of the Dongmyung and Dangun, the archaeological surveys in North Korea were criticized for their selective discoveries and arbitrary interpretations. This further supports the necessity for joint excavations and academic exchanges between South and North Korea.
