Abstract

This writing was prepared to figure out structure, constructing processes and stagespecificchange shape appearance on stony collecting basin in ancient mountain fortress. Collecting basin was located on valley, slope or ridge and hill top in mountain fortress, thebasin on valley counts for the highest percentage(85%) of all. Characters on structure of collecting basin are classified by plan/cross section shape,floor facilities, scale etc. Anaylzed character with different structure is as follows; Squarecollecting basin is linear in cross section shape. There’re floor facilities by using untouchedground, superior rate in the 500~750cm range on the scale. Rectangular collecting basinhas straight line type & reverse-trapezoid shape in cross section shape, floor facilitiesby using untouched ground and superior rate at more than 1500cm on the scale. Circlecollecting basin has reverse-trapezoid shape & steps in cross section shape, floor facilitiesby using rammed clay earth and superior rate in the 500~750cm range on the scale. Ovalcollecting basin has straight line type & reverse-trapezoid shape in cross section shape,floor facilities by using untouched ground & using rammed clay earth and superior at the750~1000cm & 1000~1500cm range on the scale. There’re so much adjuvant archaeologicaldata we can grasp anaylzed result and constructing processes. And so the processes aredivided into 8 steps. The change process of collecting basin is explained to divide into 4 steps. The firststep, it’s time to start constructing stony collecting basin in ancient mountain fortressfrom the beginning of the 5th to the beginning of the 6th century. At the second stage,it’s construction structurally spread in a wide variety from the middle of the 6th to thebeginning of the 7th century. Step number three is the constructing structure that it’s circlein plan shape, steps in cross section to range focuse on the Southern coast from the middleof the 7th to the middle of the 8th century. And fourth and last stage, the construction wasrapidly slumping from the latter of the 8th to the middle of the 9th century. The changeprocess of collecting basin is as follows; The square is first, followed by the rectangle, thecircle and the rectangle in plan shape, the linear type is followed by followed, steps andreverse-trapezoid type in cross section. And it’s confirmed changing proportion of followingthe using untouched ground(bed rock), the using untouched ground(bed rock), the settingof flagged floor and the ramming clay earth in floor facilities. Meanwhile, step distribution aspect of the basin is distributed over focusing on the Central district in the 1st step, beingdivided into the Central and Southern district in the 2nd step and focusing on the Southerncoast in the 3rd step. It’s sure that the last 4th step is spread to Southern district.
