The Gyeongju Bunhwangsa Stone Brick Pagoda, which was built with bricks of andesite, is the oldest brick stone pagoda of Silla period. The damage patterns in the stone pagoda are pollutants such as white crust, black crust, discoloration, soil adsorption, and microorganisms, and repair materials. The damage pattern of structural factors in the Stone Brick Pagoda is a bulging phenomenon. According to the X-ray diffraction analysis, white crust are mainly consist of calcite ($CaCO_3$) and thermonatrite ($Na_2CO_3{\cdot}H_2O$) that evaporite finds in nature. Damage pattern varies depending on location of stone pagoda. The pollutants are first story body of pagoda. The microorganisms are confirmed at base, lion statues, first and second story capstone, and repair materials observed at base. The bulging phenomenon appeared on the first story body of the pagoda. Occupancy rates by damage type were higher in the order of microorganisms, pollutants, repair material, bulging phenomenon, and peeling. The highest percentage of individual damage patterns were black microorganisms (39.3%), followed by lichen (17.9%), discoloration (8.0%), white crust (5.5%), cement mortar (5.1%) and peeling (3.1%).

The Bunhuangsa stone pagoda, constructed in AD. 634, National Treasure no. 30, has been named as 'brick-copied pagoda' since the Japanese-ruling period by scholars. It is said that the Chinese brick pagoda was its precedent model, however the Bunhuangsa Pagoda is the oldest of all the Chinese-style brick pagodas except one, the Sungaksa Pagoda. The Chinese pagoda cannot have been a precedent model to copy due to its complex detail of wood vestige, as the Bunhuangsa pagoda is simple form without ornament. Domestic brick pagodas cannot have been a precedent model to copy as well, because all the domestic brick pagodas are younger than the Bunhuangsa Pagoda. Therefore, the terminology 'brick-copied pagoda' is a fallacy; it is rather that later brick pagoda copied the precedent the Bunhuangsa stone pagoda. The Bunhuangsa Pagoda is simply a piled-up pagoda of thick or thin, big or small slates of stone, facing only one smooth side and therefore needing nothing to relate to brick. The originality of the pagoda is more related to simple piled-up Indian stone stupa rather than Chinese brick pagoda. The roof form of its gradually stepped projection comes from the harmika of the summit of Indian stupa. Contrary to general history, old Silla Dynasty imported Buddhism directly from India by sea. From written national history and by temple foundation history, the Indian Buddhism evangelist possibly made influence to the erecting of temple and pagoda. The original wrong terminology has made a harmful effect gradually to the naming of mass-styled stone pagoda of only carved stepped-roof form after brick-copied pagoda. The false term 'brick-copied pagoda' should be discarded, which comes with superficial observation based on toadyism to China and colonialism to Japan. Instead of the fallacious term, this paper suggests multi-storied 'piled-up pagoda with slate stone.'

The purpose of this study is to investigate the relations between brick and stone brick pagodas in all classes of pagoda with their construction and shape. Research objects of this study are brick and stone brick pagodas of National Treasure and Treasure and masonry pagodas that are similar to brick and stone brick pagoda. This study includes checking preceding researches, drawing questions from these preceding researches, and finding answers from these questions. The results of this study are as follows. First, pagoda of Bunhwangsa Temple, the first pagoda in the Silla Dynasty, was built as a masonry pagoda, not a stone brick pagoda. Second, roofs of stone brick pagoda barrows from brick pagoda's techniques for performance of material and ease construction. Third, brick or stone brick pagodas' base have Type II that has low and extensive foundation with soil and stones usually. Forth, Korean pagodas are categorized by their materials, construction methods, and shapes. Wooden pagodas, stone pagodas, and brick pagodas are categorized by materials, post-and lintel pagodas and masonry stone pagodas are categorized by construction methods, and pitched roof pagodas and terraced roof pagodas are categorized by shapes. Fifth, masonry pagodas of Buddhism that have shape of multi-story building were developed from Doltap, traditional stone stack, and they advanced with brick pagodas and stone pagodas to terraced roof stone pagodas and post-and lintel base brick pagodas.

The Bunhwangsaseoktop is the oldest stone brick pagoda in Silla Period. The pagoda body is made by piling small brick-shaped stones trimmed from black andesite and the first-story core has a shrine, which is made by granite. In 1915 it was repaired on a large scale, but now is severely damaged. Many kind of the stone decay like flaking, granular disintegration have occurred especially on the granite surface of the pagoda. In this study have been investigated the stone decay type and its cause in relation to efflorescence on the body part. Various analysis show that the deterioration on the granite is due to the same materials that lead to efflorescence on the body stone surface. The soluble salt like sodium nitrate, calcium sulfate and sodium sulfate come from white joint mortar. This salt solution is recrystallized in the outside of the pagoda, but most of them flow down with rain. In This process the porous granite absorbes the dissolved salts with moisture into the inside by capillary action. In order to reduce this problem, therefore, white joint moral is changed with other less soluble materials. And it is necessary to take steps to prevent water from seep into the inside of the stone, because this water dissolves the white joint mortar.

The stone pagoda of the Bunhwangsa temple made by piling small brick-shaped stones. The major rock forming stone bricks are andesites with variable genesis. Rock properties of the pagoda roof stone suffer partly including multiple peel-offs, exfoliation, decomposition like onion peels, cracks forming round lines and falling off stone pieces. The stylobates and tabernacles in all the four directions the pagoda are mostly composed of granitic rocks. Those rock properties are heavily contaminated by lichens and mosses with the often marks of inorganic contamination by secondary hydrates that are dark black or yellowish brown. Within the four tabernacles and northern pagoda body situated to relatively high humidity. There are even light gray precipitate looking like stalactites between the northern and western rocks of the body Their major minerals are calcite, gypsum and clays. The stone lion standing in the southeast and northeast side are alkali granite, while that in the southwest and northwest lithic tuff. Total rock properties of the pagoda are 9,708 pieces, among the all properties, fractured blocks are 11.0%, fall out blocks are 6.7% and covered blocks by precipitates are 7.0%, respectively. The pagoda has highly deteriorated the functions of the rock properties due to physical, chemical and biological weathering, therefore, we suggest that this pagoda has need to do long term monitoring and synthetic conservation researches.

Korea is famous for a number of stone pagodas. In particular, it is noticeable that the stone pagodas came after wooden pagodas in all the Kingdoms of Goguryeo, Baekje, and Silla. Since the advent of wooden pagodas, it was during the latter half period of Three Kingdoms(especially, in the early Seventh century) that the first stone pagoda appeared at Mireuksa Temple site in imitation of the wooden ones. Now that no one can deny that Korean stone pagodas have developed, imitating the wooden pagodas. It is also obvious that the Stone Pagoda at Mireuksa site is the prototype of Korean stone pagodas. However, this study casts doubt on the theory that the stone pagodas in the Silla Kingdom originated not from the wooden pagodas, but from the brick pagodas, whereas the stone pagodas in Baekje Kingdom which has been said to come from the wooden ones. The fact that the temples and pagodas in both Baekje and Silla were erected by the same builders and technicians is one of the evidences supporting the assertion of the study. This study, accordingly, examines on the origin of the Silla pagodas by supposing the two genealogies. The first one can be summarized in chronological order as follows: starting from wooden pagodas, Stone Pagoda at Mireuksa site, Stone Pagoda at Jungrimsa site, Stone Pagoda at Gameunsa site, and Stone Pagoda at Goseonsa site. The second one, on the other hand, runs as follows: starting from bick pagodas, Stone Pagoda at Bunhwangsa, Uiseong Tapri five-storied Stone Pagoda, Seonsan Jukjang-ri five-storied Stone Pagoda, and Seonsan Naksan-ri three-storied Stone Pagoda in order. As the above genealogies show, the origin of the stone pagodas has been an controversy, especially because of the two different points of view: the one is that the roof-supporting strata(Okgaesuk-Bachim) originated from the brick structure and the ancient tomb ceiling of Goguryeo Kingdom, and the other is that the strata is a sort of the simplified design of the wooden roof structure. This study, however, takes note of the difference in length of the strata between the brick pagodas and the stone pagodas; the former stretches out its strata longer than the latter. Consequently, the study points out that the roof-supporting strata of the stone pagodas is originally a sort of modification of the wooden roof structure.

Jeongamsa Sumano Stupa(Korean National Treasure No. 332) is a brick like stone stupa and it is considered that this stupa was built in the Later Silla period or in the early part of the Koryo period, considering its structure and style. This Buddhist stupa is highly significant in Korean Buddhism since it was built to enshrine Buddhist sarira reliquaries that 'Jajang' brought from China in the 7th century, according to the 『Overlooked Historical Records of the Three Korean Kingdoms, 『三國遺事』』. However, the stupa was positioned at the very unique location. It was positioned not at the center of Jeongamsa Temple, but at the separate edifice. The location of Jeongamsa Sumano Stupa indicates that this stupa embodies the nature of Mahaparinirvana treasure palaces and that this stupa was recognized as a solemn symbol, which reflected a sarira faith. Jeongamsa Sumano Stupa is the only brick stone stupa built in Gangwon province. It is worth noticing that this stupa was mostly made of dolostones, found around this region, and thereby regional characteristics were reflected in this stupa. The other interesting fact about Jeongamsa Sumano Stupa is that there are many records available which include information about stupa's reconstruction, considering that there aren't many records of other stupas. The most representative records are 5 pieces of memorial stones which include information about when and on what ground the stupa was reconstructed as well as information about originators of the stupa. In conclusion, Jeongamsa Sumano Stupar could be regarded as the academically valuable material since it is considered very important and helpful for understanding not only the history of Korean Buddhist stupas, but also so many other things such as construction techniques, styles of brick pagoda and brick stone stupa, and such.
