Abstract

The Chuwha Mountain Fortress has a symbolic value not only because it is recorded in ≪Samguksagi: The history book of Triple Kingdom in Ancent Korea≫, but also because it functioned as governing place as well as defense role in ancient time of Miryang. Attempts have been made to understand the charicteristics of Acient Mountain Fortress in the Miryang on the based excavation result of the Chuwha Mountain Fortress, which is the center of administration and defence structure. At result, I believe that Chuwha Mountain Fortress was constructed as Governmental Organ place for the purpose of dominating this area at 7th century which was entirely occupied by Silla Dynasty. I also believe that this function continued untill Koryo Dynasty. Based on this speculation, I attempted to identify the characteristics and the place of direction organ in ancient time of Miryang prior to Chuwha Mountain Fortress. The results shows that, the center of Triple Kingdom period in Millyang region was not in Miryang-up city, but bubuk-myon region which is north of Miryang-up, specifically Gasan-ri Mountain Fortress in that area. However, this Mountain Fortress is different from the typical fortress of Silla Dynasty type. Accordingly, to identify the characteristics of this Mountain Fortress, I investigated when ancient Miryang area was entirely absorbed by Silla Dynasty, through the analyses of remains and historical documents. At a result, it was concluded that the remains of Gasan-ri Mountain Fortress was excavated in adjacent wolsan-ri tombs. It can be speculated that the remains were from 5th to the end of 6th century A.D. and that in this area the new type of pottery after Samhan(Three-han) period was basically a Silla pottery type. Therefore, it is highly probable that Gasan-ri Mountain Fortress was constructed by Silla Dynasty. The investigation of documents records also shows that Cheongdo and Miryang region was included at early time by Silla Dynasty and that there were no currently existing great mound tombs unlike other areas. Hence, it is quite likely that Gasan-ri Mountain Fortress, which was included in earlier time by Silla Dynasty, was constructed before the characteristics of typical Silla Fortress was established. And I noticed that Changnyeong and Kimhae which were included in Silla Dynasty in relatively earlier time have fortresses with similar characteristics. They were classified into two groups: the first group was an early type Mountain Fortress built by stone, and the other group was an expansion type Mountain Fortress built by stone. The early type Mountain Fortress built by stone such as Gasan-ri is constructed at 5th the end～6th century. After 7th century, the expansion type appeared such as Chuwha Mountain Fortification, and that is bigger and includes the peak of a mountain and valley just like Gorobong type Mountain Fortification of Koguryo Dynasty. It is highly probable that the change of scale in the Mountain Fortress was made after Gaya area was entirely included by Silla and because there was an emphasis on a stable and permanent direction organ in this area.
