A Study Fortification Angle of the stone Castle of the Period of the Silla : Focucing face stone of the body Angle
According to the Cultural Heritage Administration's statistics, about three hundred(300) various castles are scattered all over the country.
This study is to fractionize the typical style for country with the Stone Castle of the Period of Silla selected by this study as the central subject and to classify its characteristics, which will be useful research material for applying it as another verification material in addition to the chronological recording of the excavated relics in judging the early days of originating the stone castle, etc.
First, our Stone Castle was originated from Goguryeo Dynasty in the ancient times and it's appeared in the early days the ways of building the Baekje Dynasty-lined and Goguryeo Dynasty-lined stone castles are nearly the same. In the later days, the Goguryeo-lined stone castle began to use the similar way of constructing the castles with Silla Dynasty-lined castle based upon wooden castle construction Second, Goguryeo-lined castle was built on the basis of mud castle construction like Guknae-sung(castle) and, it's appeared, in its later days it was changed to Silla-lined stone castle. In early days of Baekje Dynasty the castle was built in the basis of mud castle construction and in its later days their castle was developed to ston overray mud castle.
Third, as the result of analysing the angle of constructing more than one hundred (100) castles, the castle whose construction angle is less than 10°was identified as Silla-lined and 10～19°as Goguryeo-lined and more than 20°as Baekje-lined.
Fourth, this study with executing its related research selected, recorded & introduced only places which the time of the peculiar construction of the Three States appeared on a part of the researched places is identified based upon the archeological specimens.
This study is to file and describe the findings researched as the aboves, and some raise objections of Guyhyungsung of plate-stone building for special castles and Yogo style castle construction. Judging that by visual building technique instead of its structure, the conclusion of the pending question was left for future settlement. As far as the Korean castles all about are concerned, the fact that all the stone castles were remodelled & repaired into Silla-lined castles according as the Three States in the ancient times were unified and led to the Unified Silla might make the conclusion of the pending question obscure. If, however, we excavate and research the whole of the castles concerned all-inclusively by division, as far as its simplicity is concerned, any different factors such as building technique for each division, etc. were discovered and, therefore, it's considered that this study will be useful and of a great help to derive out wider and more reliable judgment of chronicle discrimination of their initial construction and improvement, etc.
