The purpose of this study is to investigate the history, space structures, blueprint, and techniques of the construction of Nam-hea city walls. Nam-hea city walls were relocated in 1439 from Whagumhun-Sansung(火金峴山城) to the present site, nearby Nam-hea Um.(南海邑) The city walls were rebuilt after they were demolished during Japanese invasion on Korea in 1592 and their reconstruction was also done in 1757. At present, the city walls only partially remained due to the urbanization of the areas around them. A plane form of the City wall is a square, and the circumference os approximately 1.3km. According to the literature, the circumference of the castle walls is 2,876尺, the height is 13尺, and the width is 13尺 4寸. Hang-Kyo(鄕校). SaGikDan(社稷壇), YoeDan(厲壇), SunSo(船所) which is a harbor, as well as government and public offices such as Kaek-Sa(客舍) and Dong-Hun(東軒) existed inside the castle walls. Inside the castle walls were one well, five springs, one ditch, and one pond, and in the castle walls, four castle gates, three curved castle walls, and 590 battlements existed. The main government offices inside castle walls were composed of Kaek-Sa, Dong-Hun, and Han-Chung(鄕廳) their arrangements were as follows. Kaek-Sa was situated toward North. Dong-Hun was situated in the center of the west castle walls. The main roads were constructed to connect the North and South castle gate, and subsidiary roads were constructed to connect the East and West castle gate. The measurement used in the blueprint for castle wall was Pobaek-scale(布帛尺:1尺=46.66cm), and one side of it was 700尺. South and North gate were constructed in the center of South and North castle wall, and curved castle walls was situated there. One bastion was in the west of curved castle walls and two bastions were in the east of curved castle walls. The east gate was located in the five eighths of in the east castle wall. Two bastions were situated in the north, on bastion in the south, one bastion in the south, and four bastions in the west castle wall. The castle walls were constructed in the following order: construction of castle field, construction of castle foundation, construction of castle wall, and cover the castle foundation. The techniques used in the construction of the castle walls include timber pile(friction pile), replacement method by excavation.

This study examined the construction method shown in literatures and materials discovered in rampart, barbican and guard platform for Cheongdo-Eupseong castle which was constructed immediately before Japanese Invasions of Korea (1592-98). According to the result of the examination, the construction method used in the coastal areas and inland areas of Gyeongsang province in the early Joseon period was applied to the rampart, barbican and guard platform in the east and north castle walls, which was constructed earlier than other parts of Cheongdo-Eupseong castle. However, from the western end of the northern castle wall, which was later constructed, to the western castle wall was rebuilt using a construction method different from the method applied to the parts that were constructed earlier after Japanese Invasions of Korea. Cheongdo-Eupseong castle was constructed on a flatland on a large scale and at a low height under unreasonable pressures to construct the castle in a short period of time for military defense as well as civil agitation in the imminent situation just before the outbreak of Japanese Invasions of Korea. In addition, various methods of constructing Eupseong castle utilized at that time were used together, and barbican and guard platform were built generally focusing on rapid completion and convenience, using other methods than the one mainly used at that time. This is the reason why there was a difference in the characteristics of the method and period of castle construction between Cheongdo-Eupseong castle and other Eupseong castles in the coastal areas and inland areas of Gyeongsang province.

The purpose of this study is that it is made clear the construction method of Japanese Castle Architecture in Korea as I study the construction method of Suncheon-Japanese Castle(順天倭城) in those days of Jeong-yu Japanese Invasion. Moreover, I intend to analyze the similarity and the difference between Suncheon-Japanese Castle and Korean Castle Architecture by a comparative study. The result of the study is showed that Suncheon-Japanese Castle seemed to be built with the object of a long time stay rather than it was of strategic importance for the national defense. In addition, it was different from other Japanese Castle in Korea because the watch tower(天守閣) of it stood in the middle of stronghold and the watch tower stronghold dividing the round of it while that of it stood the comer of stronghold. The face stone used in important part of watch tower, gate, and so on was mostly a trimed hexangular stone. On the other hand, the face abbuting on the Gulf of kwang-yang was made of naturally wild face stone. The stone cleared traces of Si-hyeol(矢穴) and domestic Castle in Japan was also made of this method after Im-Jin Japanese Invasion. According to the construction method, the wall of castle made use of the Netak(內托) method except the gate, the support stronghold and the watch. The early mountain castle in Korea have this construction method in common.

The purpose of this study ins to verify the characteristic location of Byungyoung Castle, physical type, inside spatial organization, and the scheme of Byungyoung Castle. The study utilizes historic literature, ancient maps related to Byungyoung Castle, topographical and cadastral maps which were published under the rule of Japanese Imperialism Castle, topographical and cadastral maps which were published under the rule of Japanese Imperialism and the topographical maps which were made recently by National Geographic Institute with various scales. The methodology of the study is to interpret the contents from the historic literature on the site map. The methodology of the study is to interpret the contents from the historic literature on the site map. The result of the study is as follows; Byungyoung Castle does duty as a defensive base for the entire country and has a specific character of location that has the dual function of a mountain fortress for national defense and of a village fortress for the town. Byungyoung Castle has four gates on four sides and has a oval shape very close to a circular form. The road construction inside the castle is composed basically of a cross shape. Byungyoung is located in the northwest area of this major road system. The private houses that lie along the north-south road are build up at the core area of the lower level and the town market built up around the south gate becomes the heart of life for the people. Schematically, it has the same pattern as regular village fortress, in that the houses for the guests and the houses for the public office are arranged to the east and the west. It is considered that there is certain functional parallel between Byungyoug Castle and Ulsan castle because there are no facilities for sacrificial rites no institutional budding.

Periodically, the Japanese Castle was created in the domestic of Japan and then 2 Invasions into Chosun was started. The Japanese Castle in the domestic of Japan was repaired several times by the building boom of castle before & after 2 invasions and so the initially-built type of castles was changed. Accordingly, there are much difficulties to understand the original shape of Japanese Castle. Through the Japanese Castle within Korea called as the fossil of Japanese Castle, I would like to examine & consider its building period and characteristics. The terminology called as [Two Side Stone's Wall] is that of castle which is not acknowledged in the Japanese Academic Circles. However, it means the two-fold wall of Japanese Castle which was widely applied to the fortification way in the Age of Japan Edo. The terminology of [Sori] says the stonework curve in the corner of Japanese Castle which is indicated best in the Japanese Castle. It calls the curve as like the fan frame. [Curb Stone's Wall] says the type of castle wall constructed with over 1 face in wall body of Japanese Castle. (1) About classifying the construction period of Japanese Castle, the curb stone's wall and the castle having no two side stone's wall must consider the building period as that of Japanese Invasion of Korea in 1592. If there was [Sori], the two-side stone's wall was used and the place which supported the documentary data, in particular, the place having the record of contraction is considered to be confirmed as the castle constructed in the period of Japanese Invasion of Korea in 1597. (2) The two-side-type stone's wall shown in the Modern Japanese Stone Castle is difficultly considered to be generated from the Japanese Castle at the period of Japanese Invasion of Korea in 1592 and in 1597. (3) The beautiful [Sori] shown in the Modern Japanese Stone Castle was started from the Japanese Castle of Korea at the period of Japanese Invasion of Korea in 1597. It is difficultly considered which its indication was firstly generated by the Chaesung-Folded Segment Structure.

Through reinvestigations of early years of King Young-Joe provincial castles, Jeonju Eupsung, this study seeks to broaden the understanding of castle construction of the later period of Chosun Dynasty. Jeonju Eupsung was established by reform-minded king and his loyalist Cho, Hyun Myung. Their new conceptual framework for reconstruction of Jeonju Eupsung was affected by Yoo, Hyung Won, a realist scholar of 17th century. It is obvious that adopted new administrative systems of financing, building and maintaining of Jeonju Eupsung were based on the his theories of castle. This study demonstrates that Jeonju Eupsung built by Cho, Hyun Myung, during the early years of King Young-Joe were based on those new concepts and systems of the new age. The study shows that the designer of this castle had in mind efficient construction design and execution and effective defense of provincial towns located on flat ground. And, the study explains how those original designer sought higher productivity through greater localization of securing resources and more detailed and improved organization of construction responsibilities. In short, this study seeks to prove that the provincial castles of the early 18th century reflected the new thinking on practicality that was spreading throughout the society of Chosun Dynasty at the time.

The purpose of this study is to analysis chromaticity, granulometry, main chemical composition and mineral crystal structure of wall soils excavated from Poongnatoseong Earthen Castle using color reader, XRD, particla size analyzer. The analysed soils of Poongnatoseong Earthen Castle were yellowish brown and isabella. All samples were sands or sands including silty soil(SW~SC) and showed similar granulometry, chemical composition and mineral crystal structure, which were characteristics of construction materials suitable for modern road or airstrip. As resulting in comparison with 4 factors from chromaticity, granulometry, main chemical composition and mineral crystal structure, we decided that the control soils(PNS) near by Poongnatoseong Earthen Castle were not to be used for the castle wall construction We presumed that there was a huge soil distribution area for the wall construction around Poongnatoseong Earthen Castle. For further study, we will make a comparison analysis all kinds of soil characteristics. And then we can understand correctly about wall soils producing area, construction method, repair method and time of Poongnatoseong Earthen Castle.

This study aims to clarify the transformation of urban spatial structure around old castle in cheong-ju city. The urban spatial structure is composed with road system, block division, and lot system with original cadastral map in 1913 and 2011 GIS. Transformation of road system is classified into control of road line, construction and extension of road. Construction of arterial road was divided into Nam-juro and Mang-sunro with 2 blocks and lot system was destoyed. Transformation of block has not been developed except 4 blocks. The 4 blocks were divided into east-west or north-south direction and became 8 blocks. Transformation of lot system is classified into maintained, subdivided, and destroyed lots in shape and size of lots. Maintained lots were found in large lot in size for public office and park. Subdivided lots were mainly represented with the existing main road, an active alleys, and so on. Destroyed lots by road construction and extension were showed in Nam-juro. Although all these transformations are used to enhance urban spatial structure. The old systems have remained around old castle in cheong-ju city.

Generally the dynamic characteristics of stone wall structures depend on several factors such as contact, the type of interlocking bonding stones, and the filling materials. This paper describes a non-destructive technique for diagnosis of historic masonry stone structures using the measurement of natural frequency technique. For this purpose, the castle wall of Nag-An Folk Town located in Sunchon, Korea was selected as a model. The Nag-An Town Castle is one of the well maintained historical remains constructed in the Chosun Kingdom of Korea. The construction started in 1397 A.D and was finished in 1626 A.D. The non-mortar castle wall is 1470m long and the average height is 4m with a width of 3 4m. The exterior of the wall is bonded with 1 2 m rectangular rough-faced stone and the inside of the wall is filled with gravel. The traditional village still remains inside the Nag-An Town Castle, and they have a regional food festival every October. Transverse vibrations were measured at 8 points around the castle. The measured natural frequency of the first mode was 26Hz 41Hz, and the shear modulus of filling material was 2.142 x $10^3$ ~ 8.915 x $10^3$kgf/$cm^2$ . With these results, it may be assumed that the filling material is gravel or a sand-gravel mixture. It is expected that the information provided by this paper will be useful for addressing the maintenance problems of the old castle walls.

There were many researches on marine transportation and granaries, most of which focused on the historical establishment and organization of the marine transportation. However, a few researches were conducted on the architectural aspects. Hence the purposes of this study are to investigate the following matters: first, documents and relics concerning the tribute granary castle at Cape Gongse in Asan, a typical granary during the Joseon Dynasty, were investigated to academically understand the castle's establishment and historical background; second, the dispositional characteristics of the granary and the castle, including its adjacent facilities, were investigated to review its archaeological value; finally, basic materials were provided for systematical preservation and management these relics. As for the research method, the author referred to and analyzed sundry records and old maps, and ascertained in detail historical evidence through residential testimonies and the on-the-spot surveys. In addition, the author investigated the dispositional characteristics of the tribute granary castle at Cape Gongse by analyzing its exact size and shape, based on the old documents and an actual survey of the castle remains. The characteristics of the tribute granary castle at Cape Gongse may be summarized as follows. First, tribute granary at cape Gongse is a only tribute granary which has a granary and castle. second, the tribute granary castle at Cape Gongse has a curvilinear shape, like a gourd dipper; a large circle surrounding the village and a small circle surrounding the area of Mt. Shinpoong both meet up with it. Third, the construction type of the tribute granary castle at Cape Gongse is in a style similar to a town castle or a battle camp castle located in the coastal regions. As for its locational conditions, however, the east gate, presumably an incoming and outgoing route to the granary for vessels, was a feature unique to the marine granary castle. Fourth, the tribute granary at Cape Gongse had a granary of eighty kan in 1523 and, in addition, there were also Bongsang-cheong, Sa-chang, Joseon-sobakcheo, Chimhae-dang, and more, not to mention many privates houses in the castle. The granary is located in the center of the tribute granary castle, where Gongse Nonghyub is currently located. The location of the government offices seemed to be on the northern ridge. Fifth, the tribute granary castle at Cape Gongse is a valuable relic that offers insight into marine transportation, tribute granaries, and tribute granary castles during the Joseon Dynasty. It has special archaeological value because it was one of only a few tribute granary castles that served to protect the tribute granaries.
