This study aims at the examinations on the dwelling sites of the Iron Age which were excavated in the Jeonnam Province. The dwelling sites which were examined in this study are divided by two regions such as the western part and the eastern part. And then, the western part is subdivided into three regions such as the west coast area, the upstream area of Yeongsan River, the downstream area of Yeongsan River, the eastern part is subdivided into two regions such as the Boseong River basin, and the Seomjin River basin. Firstly, the dwelling sites which were excavated in the Jeonnam Province are classified into three periods according to the location, the constructional characteristic of the dwelling sites and the character of the remains which had been excavated. The first period corresponds to the era from the 2nd century B.C. to the 1st century A.D.. It is the stage where the new culture of the Iron Age had flowed in the existing culture of the Bronze Age. As for the form of plane, it appeared that a round shape was taken for the most part. The area was small sized. The hearth was located at the center. As for the remains, kinds of plain coarse pottery and the arrowhead without tang were confirmed. The second period is the era from the 2nd century A.D. to the 3rd century A.D.. They were located at the upper part of hills and on the slopes. The shape of plane was rectangular type. The area ranged from 5㎡~15㎡. The direction of long axis was related with the location. The hearth was the style that had no facilities, and it was made at the one side of the wall side to be used. The bottom was tamped with fire or clay. As for the remains, friable earthenwares that had low plasticity temperature have been being confirmed. Some kinds of accessories like jade started to be excavated. The third period corresponds to the era from the 4nd century A.D. to the 5th century A.D. As for the location of dwelling sites, they were built at the flat land. The area ranged from 10㎡~25㎡. The trace of round holes of 4 column style appeared. The hearth was the type that had no facilities, and it was made to be inclined toward the one side of the wall side. As for the remains, they became to belong to the point of time when the attribute of the second period continued partially, and new forms of earthenwares appeared at the same time. The capacity of kinds of earthenwares became to be large compared with that of the previous stages. And the excavated rate of the hard earthenwares became high, too. In addition, the kinds of earthenwares became diverse, and the funerary objects of tombs were excavated as well. Next, the regional characteristics were investigated by dividing into two regions such as the western part and the eastern part. The western part which included the west coast area, the upstream and the downstream area of Yeongsan River was distributed at the ridge, slope and flat ground of hills. As for the form of plane, square or rectangular types showed the high rate of possession. But, the round style including oval shape was extremely very few. The area ranged 5㎡~25㎡, which showed even distribution. The large-sized dwelling sites of more than 100㎡ were also being confirmed. The direction of long axis was distributed according to the location of dwelling sites. The hearth was showing the typical tendency which used one side of the north wall. The facility of wall drains were confirmed at more than 50% of the total dwelling sites. The Jar with double mouth rim among the excavated relics, was being excavated at the remains of the west cost area and the upstream area of Yeongsan River. The hole jar with wide mouth was the unique element which could be seen only in this region. The eastern area including the basin of Boseong River and the basin of Seomjin River were all located at the basin type of flat land. As for the shape of plane, the square or rectangular type took the main part, however, the round or oval type continued until the latter period. The area was distributed evenly with the size ranged from 5㎡~25㎡. But the size more than 100㎡ could not be confirmed. The hearth was also showing the typical tendency which used one side of the north wall. The bottom was tamped with fire or clay into about 2~3㎝ thickness. The facility of wall drains were confirmed at less than 5% of the total dwelling sites. The jar with two lugs among the excavated relics was the kind of pottery which was excavated centrally at the basin of Boseong River. Finally, the life style was investigated by classifying into clothing. food and shelter. As for the location of dwelling sites among the changes of housing life, the tendency where houses were built at the ridge and the slope of hills was changed. They were gradually moved to the flat land so that they were built with forming villages. As for the shape of plane surface, the rectangular typed house was built. The long axis did not prefer a particular direction. Instead, it showed even distribution according to the location of dwelling sites. As for the area, the dwelling sites that corresponded to the size ranged from 10㎡~25㎡ took the most part, which showed the fact that they led a life with the trend toward the nuclear family. Besides, they led agricultural and fishing life. It could be seen that textile was woven at each residence, and decoration was put up with jade. With the fact mentioned above, the cultural aspects of the Iron Age in the Jeonnam Province will be investigated in detail through the dwelling sites.
